Zwitterionic polymers, consisting of polymer backbone of ester or amide (meth) acrylic acid or pyrrolidinium, exhibit excellent non-fouling property, and have received great attention since last decade. However, these polymers lack important biodegradability for their application in biomedicine or marine field. Developing degradable zwitterionic polymers will solve problem associated with traditional zwitterionic polymers and increase their potential to be used in biomedicine for achieving both non-fouling and degradability. Herein, we present a comprehensive review describing various strategies developed till now for achieving degradable zwitterionic materials. Synthesis and applications of zwitterionic polymers based on various biodegradable polyesters, polypeptides, and natural polysaccharides (chitosan, starch and cellulose) have been critically reviewed and summarized. The basic structural characteristics and properties of different types of zwitterionic materials and biodegradable zwitterionic materials have also been introduced briefly. To the best our knowledge, this is the first review focusing on biodegradable zwitterionic materials.

Application of 52722-86-8, A catalyst don’t appear in the overall stoichiometry of the reaction it catalyzes, but it must appear in at least one of the elementary reactions in the mechanism for the catalyzed reaction. 52722-86-8, Name is 1-(2-Hydroxyethyl)-2,2,6,6-tetramethylpiperidin-4-ol, molecular formula is C11H23NO2.

With the objective of studying the conformational and macrocyclic effects of selected metal chelates on their peroxidase activities, Cu2+ and Fe3+ complexes were synthesized with a macrocyclic derivative of ethylenediaminetetraacetic acid and o-phenylenediamine (abbreviated as edtaodH2) and its new open-chain analogue (edtabzH2). The Fe3+ complex of edtaodH2 has a peroxidase-like activity, whereas the complex of edtabzH2 does not. The X-ray study of the former shows the formation of a dimeric molecule {[Fe(edtaod)]2O} in which each metal with an octahedral coordination is overposed over the macrocyclic cavity, as a result of rigid macrocyclic frame, to form an Fe-O-Fe bridge; the exposure of the central metal to the environment facilitates the capture of oxygen to drive the biomimetic activity. The peroxidase-inactive Fe3+ complex consists of a mononuclear complex ion [Fe(edtabz)(H2O)]+, the metal ion of which is suited in a distorted pentagonal bipyramid to be protected from environmental oxygen. The copper(II) complexes, which have mononuclear structures with high thermodynamic stability compared with the iron(III) complexes, show no peroxidase activity. The steric effects play a fundamental role in the biomimetic activity.

Polymer-based monolithic materials with interconnected porous structure have received much attention as high-performance matrices for enzyme immobilization. The present work describes immobilization of horseradish peroxidase (HRP) onto a polymethacrylate-based monolith which was fabricated by thermally induced phase separation (TIPS) method. The poly(glycidyl methacrylate-co-methyl methacrylate) (PGM) monolith was modified with adipic acid dihydrazide (AADH) and ethylenediaminetetraacetic dianhydride (EDTAD) to yield carboxyl group-bearing PGM (PGM-COOH) monolith. This monolith was reacted with N-hydroxysuccinimide (NHS) to activate the carboxyl groups on the monolith and further modified with HRP. The immobilized HRP showed much higher thermal stability than the free one. Furthermore, the immobilized HRP could be reused for at least 6 times with the remaining activity of 52%. The PGM monolith may have a high potential as a solid support for enzyme immobilization.

Magnetic baker’s yeast (MB) was prepared using glutaraldehyde cross-linking method and chemical modification with ethylenediaminetetraacetic dianhydride (EDTAD). The fabricated EDTAD-modified magnetic baker’s yeast (EMB) was then employed to remove methylene blue. Comparative adsorption of methylene blue by EMB and MB was systematically investigated with respect to pH, contact time, initial concentration and reaction temperature. The mechanism of methylene blue adsorption by EMB and MB was investigated by SEM, FTIR and Special surface area using methylene blue method. The results revealed that Fe3O4 nanoparticles were steadily cross-linked/incorporated with baker’s yeast biomass and the EDTA was modified on the surface of the magnetic baker’s yeast. The equilibrium adsorption data were fitted better by Langmuir isotherm, and the specific surface areas were 42.953?226.07 m2/g for MB and 94.972?499.85 m2/g for EMB, respectively. Kinetic studies suggested that the pseudo-second-order model was suitable to describe the adsorption process. Thermodynamic studies indicated that the adsorption was feasible, spontaneous and endothermic. The recovery efficiencies were above 80% by using 0.1 M HCl.

It is known that synthetic polymer plays a big role in various applications. One of its potentials is to remove heavy metal ions through single batch adsorption. Adsorption behavior and mechanism of synthetic polymer are the two main focuses in this research. The synthetic polymer of Poly(AN-co-AA) has been successfully polymerized, modified with hydroxylamine hydrochloride and removed Cd2+ and Pb2+. The poly(AN-co-AA) and amidoxime (AO) modified poly(AN-co-AA) were characterized by Fourier Transform Infrared Analysis (FTIR), microanalysis, Scanning Electron Microscopy (SEM) and Thermogravimetry (TGA). At pH 9, the percentage removal for Cd2+ (90%) and Pb2+ (98%) were the highest with adsorbent dosage at 4 gL?1 and 8 g L?1, respectively. The experimental data for Cd2+ (20 mg g?1) and Pb2+ (125 mg g?1) were fitted well by Sips and Freundlich isotherms model, respectively. The adsorption rate for both Cd2+ and Pb2+ were stated by using Lagergren pseudo-first order.

The increase in the volume of agricultural and agroindustrial waste, associated with improper disposal, is a growing worldwide problem. The recovery of those residues is of crucial importance, since it reduces environmental impacts, protects public health, and allows the addition of value to the materials. One of the ways of exploiting adsorbents is related to the capacity of some wastes to be used as alternative adsorbents in the efficient removal of microcontaminants in aqueous systems. This work assessed the use of agricultural and agroindustrial residues: maize straw, wheat straw, soybean straw and soybean hulls for the production of alternative adsorbents to remove iron (Fe) and manganese (Mn) in water. For each residue investigated, two different polymers were obtained for use as adsorbents, a natural polymer (cellulose/lignin) and an EDTA-modified polymer (ethylenediaminetetraacetic acid). The adsorbents were characterized through FTIR (Fourier transform infrared spectroscopy) and nitrogen content. To evaluate the efficiency of the adsorbents, kinetic tests in batch mode and determination of Lagergren pseudo-first and pseudo-second order kinetic constants were performed. The results found that the modified polymer obtained from soybean hulls (SHE) showed increased Fe (96%) and Mn (88%) removal rate, in which the pseudo-second order kinetic model presented closer results between the experimental adsorption rates and the calculated ones for the two microcontaminants under study. In general, the modified soybean hulls proved to be a promising alternative adsorbent for the removal of iron and manganese in water treatment.

Chitosan, which is derived from chitin by deacetylation, is one of the most promising biopolymers for adsorption of metal ions from diluted waste streams. By functionalization of chitosan with ethylenediaminetetraacetic acid (EDTA) or diethylenetriaminepentaacetic acid (DTPA) groups, it is possible to obtain a material that is much less soluble in acidic aqueous solutions than native chitosan. The coordinating EDTA and DTPA ligands are very efficient for binding of rare-earth (lanthanide) ions. The functionalization was achieved by reaction of chitosan with EDTA bisanhydride or DTPA bisanhydride. The binding of lanthanide ions to functionalized chitosan was investigated by FTIR (binding of Nd3+) and luminescence spectroscopy (binding of Eu3+). Comparison of the luminescence decay times of the europium(iii) coordinated chitosan complexes swollen in water and in heavy water allowed determination of the hydration number of the coordinated Eu3+ ion. Batch adsorption tests for the uptake of neodymium(iii) from aqueous nitrate solutions were performed for EDTA-chitosan and DTPA-chitosan. Different experimental parameters such as the adsorption kinetics, loading capacity and pH of the aqueous feed were investigated. The modified chitosan materials are much more effective for adsorption of rare earths than unmodified chitosan. It was shown that adjustment of the pH of the aqueous feed solution allows achieving selectivity for adsorption of rare-earth ions for mixtures containing two different ions. After stripping of the metal content, the modified chitosans could be reused for new adsorption experiments. Medium pressure liquid chromatography (MPLC) with DTPA-chitosan/silica as the stationary phase and a dilute nitric acid solution as eluent was used for the separation of the following mixtures of rare-earth ions: Nd3+/Ho3+, Pr3+/Nd3+ and Pr3+/Nd3+/Ho3+. The experiments show that separation of the rare-earth ions is feasible with DTPA-chitosan/silica, without the need for using solutions of chelating agents as eluents.

A new positively thermo-sensitive hydrogel was designed and synthesized by a condensation polymerization reaction of ethylenediaminetetraacetic dianhydride (EDTAD) and piperazine (PA) to give poly (ethylenediaminetetraacetic dianhydride-co-piperazine) (PEP). The obtained polymers’ structure was characterized by FTIR and 13C NMR. The backbone of the polymer linked by amide bond and abundant of carboxyl groups as pendant group could form strong intermolecular and intramolecular hydrogen bond at lower temperature and dissociate at higher temperature, resulting in the polymer with thermo-sensitivity. The aqueous solution of PEP at lower temperature (<20 C) showed micro-gel formation and transformed to transparent solution at higher temperature (>40 C). Transition temperature shifted to higher value with the increasing of concentration. The hydrogel exhibited reversible phase transition and the transmittance change was not weakened by multiple temperature changes.
