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.
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.Application In Synthesis of 1-(2-Hydroxyethyl)-2,2,6,6-tetramethylpiperidin-4-ol, you can also check out more blogs about52722-86-8
