A chitosan resin derivatized with Schiff bases was synthesized by using a crosslinked chitosan (CCTS) as base material. We first synthesized N-benzylidene chitosan (CTB) by the reaction of benzaldehyde with chitosan. After this reaction crosslinking was carried out in the usage of epichlorohydrine (ECH) as a crosslinking agent. The Schiff base was removed by reacting diluted ethyl alcohol hydrochloride...
One of the major applications of chitosan and its derivatives is based on its ability to bind strongly toxic metal ions. In this work, two novel polymeric ligands were synthesized to investigate the adsorption properties of Cu(II), Pb(II), Zn(II) and Ni(II) ions in an aqueous solution. To prevent the reaction between as the C2 amine group of chitosan and ECH, the C2 amine group was protected N-benzylidene...
