Synthesis of Glycoconjugated Polymer Based on Polystyrene and Nanoporous beta-Cyclodextrin to Remove Copper (II) From Water Pollution

Abstract

A novel glycoconjugated polymer, poly (styrene-co-(cyclodextrinmethyl) styrene), was synthesized from reacting poly (styrene-co-(chloromethyl) styrene) with nanoporous -cyclodextrin in the presence of pyridine in DMF as the solvent. The obtained glycoconjugated polymer was able to solubilize some hydrophobic guest molecules such as cholesterol and also could capture some heavy metals through their nanocavities. In practice, to the solution of water containing hazardous heavily metal, the previously obtained copolymer was added then with addition acetone or methanol the complex was precipitated and purified. The loading amount of captured metals through copolymer was evaluated using UV-vis spectroscopy. The DSC data provided direct evidence of the thermal stability of the synthesized copolymer. The structure determination of the obtained copolymer was characterized using common spectroscopic methods such as H-1 NMR and FT-IR.
