Effective removal of Pb(II) using magnetic Co0.6Fe2.4O4 micro-particles as the adsorbent: Synthesis and study on the kinetic and thermodynamic behaviors for its adsorption

Magnetically separable adsorbent composed of Co0.6Fe2.4O4 micro-particles were successfully prepared by thermal decomposition of the Co0.6Fe2.4C2O4¡¤2H2O. The as-prepared samples were characterized by X-ray diffraction (XRD), thermogravimetric analysis (TGA), inductively coupled plasma-atomic emission spectroscopy (ICP-AES), field emission scanning electron microscopy (FESEM), transmission electron microscopy (TEM), high-resolution TEM (HRTEM), X-ray energy dispersive spectroscopy (EDS). The specific surface area of the sample is determined to be 97.155m2g-1, with uniform pore size distribution centering at about 7.432nm. The as-obtained Co0.6Fe2.4O4 micro-particles exhibits ferromagnetic behavior at room temperature, which makes it magnetically separable under external magnetic field. The as-obtained magnetic Co0.6Fe2.4O4 micro-particles exhibits excellent adsorption capacity and high adsorption rate for the removal of Pb(II) in aqueous solution. The maximum adsorption capacity of Pb(II) is up to 80.32mgg-1 and 88% of the Pb(II) can be removed within the initial 30min of contact time. The effects of contact time, initial pH, ionic strength and temperature on the adsorption behavior of Pb(II) were systematically investigated. The kinetics of the adsorption process follows the pseudo-second-order model and is controlled by the film diffusion process. The equilibrium data can be fitted well using the Langmuir isotherm model, suggesting that the uptake of Pb(II) ions is a mono-layer adsorption process. Meanwhile, the mean free energy E calculated by D-R isotherm model demonstrates that the adsorption process is implemented via the chemical ion-exchange mechanism. The thermodynamic studies illustrate that the adsorption process is endothermic and spontaneous in nature.

I hope this article can help some friends in scientific research. I am very proud of our efforts over the past few months and hope to 52722-86-8, help many people in the next few years.Quality Control of: 1-(2-Hydroxyethyl)-2,2,6,6-tetramethylpiperidin-4-ol

Natural superabsorbent plastic materials based on a functionalized soy protein

A natural superabsorbent polymer (SAP) material based on an acylated soy protein was studied as a green alternative to non-biodegradable SAP. In order to obtain the natural SAPs, different amounts of succinic anhydride were used as acylating agent. Once the functionalized protein was obtained, it was mixed thoroughly with glycerol and then molded through a lab-scale injection molding device. Water uptake of samples obtained reached values much higher than those based on unacylated protein. Moreover, a greater extent of the acylation reaction led to higher water uptake values for the corresponding SAPs, probably related to their higher hydrophilic character. Water imbibing capacity measurements and thermogravimetrical analysis (TGA) seemed to confirm this. The presence of larger porous regions in acylated samples observed in SEM images could also play a role in their higher water uptake values. Furthermore, an increase in the extent of acylation reaction led to plastics with lower Young’s modulus and higher extensibility.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions.Synthetic Route of 52722-86-8, you can also check out more blogs about52722-86-8

Simultaneous detection and removal of cobalt ions from aqueous solution by modified chitosan beads

Abstract: In this paper, we modified chitosan beads in order to simultaneously detect and adsorb Co2+ from aqueous solution. Firstly, 4-(5-chloro-2-pyridylazo)-1,3-phenylenediamine (5-Cl-PADAB) was used as selective probe for Co2+ with color changing from yellow to pink, and the UV?Vis spectra showed that the lambdamax changed from 439 to 504?nm. Then a novel biomaterial was synthesized with 5-Cl-PADAB (metal indicator), chitosan (biosorbent) and EDTA anhydride (cross-linker and chelating agent). The analysis of Fourier transform infrared and energy-dispersive X-ray spectra proved that 5-Cl-PADAB and EDTA were successfully connected to chitosan. The modified chitosan bead was selective probe for Co2+ with a remarkable color change from white to pink, and the UV?Vis spectra showed that the lambdamax changed from 441 to 459?nm. The adsorption of cobalt ions onto the modified chitosan beads followed pseudo-second-order (R2?=?0.99) kinetics and the Langmuir isotherm model (R2?=?0.80). Comparing with chitosan beads, the qe of the modified one increased from 2.00 to 7.97?mg/g. The modified chitosan beads are promising biomaterial for simultaneous detection and removal of Co2+ from aqueous solution.

(Ethylenediaminetetraacetic acid)cerium(IV) [CeIV(EDTA)] complexes with dual hydrophobic binding sites as highly efficient catalysts for the hydrolysis of phosphodiesters

beta-Cyclodextrin (beta-CD) derivatives 1 with an amino group at C(6), C(3), or C(2) were homogeneously linked together by an ethylenediaminetetraacetic acid (EDTA) bridge (Scheme). Coordination of the linker to metal ions and cooperation of the dual cavities of 3 in binding hydrophobic guests were properly demonstrated by NMR techniques and a fluorescence-based titration method, respectively. The hydrolysis of bis(4-nitrophenyl) phosphate (BNPP) in the presence of CeIV complexes of beta-CD dimers 3 was tens of millionfold faster than that in the absence of the CeIV complexes. Hydrophobic binding of the beta-CD cavities was estimated to contribute to the catalysis by a factor of up to 520, and the type of modified sugar unit and the bridging positions influenced this cooperation between the beta-CD moieties and the catalytic metal center.

EDTA bis-(ethyl phenylalaninate): A novel transition metal-ion chelating hydroxyl radical scavenger with a potential anti-inflammatory role

Conjugation of ethylenediaminetetraacetic acid (EDTA) to ethyl phenylalaninate generates a novel radical scavenging metal-ion chelator EDTA bis-(ethyl phenylalaninate) (EBEP). The oxidation products o-, m- and p-tyrosine were isolated from hydrolysed, aqueous and aerated solutions containing EBEP, Fe(II) and H2O2. Data obtained demonstrate the potential of EBEP to act as a radical scavenging, iron-ion chelating antioxidant under physiologically relevant conditions.

High- k Gate Dielectrics for Emerging Flexible and Stretchable Electronics

Recent advances in flexible and stretchable electronics (FSE), a technology diverging from the conventional rigid silicon technology, have stimulated fundamental scientific and technological research efforts. FSE aims at enabling disruptive applications such as flexible displays, wearable sensors, printed RFID tags on packaging, electronics on skin/organs, and Internet-of-things as well as possibly reducing the cost of electronic device fabrication. Thus, the key materials components of electronics, the semiconductor, the dielectric, and the conductor as well as the passive (substrate, planarization, passivation, and encapsulation layers) must exhibit electrical performance and mechanical properties compatible with FSE components and products. In this review, we summarize and analyze recent advances in materials concepts as well as in thin-film fabrication techniques for high-k (or high-capacitance) gate dielectrics when integrated with FSE-compatible semiconductors such as organics, metal oxides, quantum dot arrays, carbon nanotubes, graphene, and other 2D semiconductors. Since thin-film transistors (TFTs) are the key enablers of FSE devices, we discuss TFT structures and operation mechanisms after a discussion on the needs and general requirements of gate dielectrics. Also, the advantages of high-k dielectrics over low-k ones in TFT applications were elaborated. Next, after presenting the design and properties of high-k polymers and inorganic, electrolyte, and hybrid dielectric families, we focus on the most important fabrication methodologies for their deposition as TFT gate dielectric thin films. Furthermore, we provide a detailed summary of recent progress in performance of FSE TFTs based on these high-k dielectrics, focusing primarily on emerging semiconductor types. Finally, we conclude with an outlook and challenges section.

Enhanced in vivo tumour imaging by EDTA-bis-GNGR functionalized core shell CdSe:ZnS quantum dot: Synergistic effect of active passive targeting

It has been shown in one of our earlier studies that the homodimeric N2S2 system enhances the biocompatibility of semiconductor core shell CdSe:ZnS quantum dots by lowering their toxicity and optimizing the steric ligand packing density. In this study we functionalize the core shell quantum dots with the same homodimeric ligand and add two moieties of GNGR (Gly-Asn-Gly-Asp) peptide which contain the NGR motif known to target the CD13 receptors in tumour vasculature. The aim is to study the influence of active receptor based targeting by peptide and passive targeting by QD nanoconjugate on tumour imaging. The core shell CdSe:ZnS quantum dot were synthesised and conjugated with EDTA-bis-GNGR ligand. The docking studies show high binding affinity of the synthesised quantum dot nanoconjugate to the CD13 receptor. The GNGR peptide was synthesised on solid phase using Fmoc chemistry, followed by its conjugation to EDTA-bis-cysteamine. The complete physicochemical characterisation of the ligand was done using 1H NMR, 13C NMR and mass. The comparative in vivo kinetics, biodistribution and tumour targeting by native GNGR, EDTA-bis-GNGR and EDTA-bis-GNGR-QD was studied in murines after radiolabelling with 99mTc. The changes observed in vivo on comparing the three are very interesting. A seven fold increase in tumour uptake is seen after nanoconjugation highlighting the synergistic effect of active passive targeting resulting in enhanced tumour imaging. This study thus opens up a new area where the nanoplatforms can be designed to get the best of both targeting and potential theranostic applications.

Fluorescence and conformation in water-soluble bis(pyrenyl amide) receptors derived from polyaminopolycarboxylic acids

Fluorescent responses and conformational changes against pH were studied on four new water-soluble 1-pyrene and 1-methylpyrene bichromophores, (ttha1py)H4, (edta1mpy)H2, (dtpa1mpy)H3 and (ttha1mpy)H4, with the objective of modifying pH-fluorescence profiles and other solution properties of 1-pyrene bichromophores, (edta1py)H2 and (dtpa1py)H3, developed previously by our group; the abbreviations with acidic protons stand for pyrenyl moieties interlinked by an EDTA, DTPA (diethylenetriaminepentacetic acid) or TTHA (triethylenetetraminehexaacetic acid) chain through amide linkages. The new derivatives exhibit emission bands of monomeric pyrene and an intense structureless excimer band; the latter responds to pH sensitively. The pH dependence of the emission intensity of the DTPA and TTHA derivatives is well correlated with species distribution determined by potentiometry. In every derivative, the completely deprotonated species Ln- is the most efficient for excimer emission, followed by the corresponding monoprotonated species LH(n-1)-. In the latter, the acidic hydrogen is located on the central amine, as confirmed by 1H NMR. The resulting hydrogen bond between amino nitrogen atoms makes the aliphatic chain rigid. Further protonation stretches the interlinking chain due to electrostatic repulsion. These conformational changes with protonation result in fluorescent on-off cycles against pH window. The switching cycles of the methylpyrene derivatives are reverse to those of the corresponding pyrene derivatives, as the CH 2 spacer between the amide and aromatic groups defines the orientation of pyrene rings. The sensitiveness of amide group to environment leads to a sharp change in excimer emission above pH ?11. The combined functions of amide and amino groups lead to the novel pH-responses.

One-pot synthesis of soy protein (SP)-poly(acrylic acid) (PAA) superabsorbent hydrogels via facile preparation of SP macromonomer

A soy protein (SP)-poly(acrylic acid) (PAA) superabsorbent hydrogel was synthesized from soy protein isolate and potassium acrylate. Alkali-treated SP was turned into macromonomer through the functionalization of its primary amine groups using methacrylic anhydride. The SP-PAA hydrogel was formed by free radical copolymerization of the SP macromonomer and potassium acrylate monomer. It was demonstrated that the SP macromonomer acted as a macro-crosslinker and no additional crosslinker was needed. The whole synthesis was conducted in a one-pot process. The chemical structure and degree of functionalization of the SP macromonomer were characterized by 1H NMR spectroscopy and UV?vis spectrophotometry, respectively. The SP to acrylic acid weight ratio at the preparation of the hydrogel was 1/3 and the SP content in the final product was 11?19%. As a result of the functionalization of SP, compressive gel strength was significantly improved, gel content was increased and extractable SP was reduced. Free swelling in distilled water was reduced for SP macromonomer gels due to increased crosslink density. The SP-PAA hydrogels displayed a stable swelling performance in buffer solutions with pH ranging from 6 to 11.5.
