Preparation of Two Calix[4]arene-Functionalized Biopolymers and Evaluations of Their Extraction Abilities Against Cr(VI)/As(V) Anions
Abstract
Two calixarene-functionalized biopolymers (calixarene-functionalized chitosan and calixarene-functionalized cellulose) have been synthesized and duly characterized using FTIR, TGA and elemental analysis techniques. Furthermore, their anion extraction behaviors at various pH values have been evaluated toward dichromate and arsenate anions. Results indicated that calixarene-functionalized chitosan against dichromate ion exhibited higher extraction capability than calixarene-functionalized cellulose. Intriguingly, although a less extraction efficiency against dichromate anion was obtained by calixarene-functionalized cellulose, the arsenate anion extraction results showed that calixarene-functionalized cellulose is more effective ionophore than calixarene-functionalized chitosan.
