Preparation of Chitosan and Epichlorohydrin Cross-Linked Adsorbents and Adsorption Property of Dyes

Abstract:

Cross-linked chitosan adsorbents were prepared by modification of chitosan with epichlorohydrin under alkaline conditions. It was showed that chitosan had cross-linked with epichlorohydrin by infrared spectrum analysis. Using scanning electron microscopy, it was observed that the roughness increased and granular material exhibited on the cross-linked chitosan adsorbents surface. Using Congo red solution as simulated dye wastewater, the adsorption properties of cross-linked chitosan adsorbent were detected. The results showed that the adsorption capacity of the cross-linked chitosan adsorbents for Congo red was higher than that of chitosan.
