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.

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.
