Abstract: The environmental pollution caused by industrial dye wastewater is serious,and the treatment of dye wastewater has become an important problem to be solved urgently. Chitosan is a kind of biodegradable natural polymer material with extensive sources,non-toxic and harmless. The functional groups such as amino group and hydroxyl group on the molecular chain of chitosan interact with organic dyes,so as it was used as a dye adsorption material. This review summarized the research status of chitosan-based adsorbents,including the research progress of chitosan,chitosan derivatives and chitosan modified materials as dye adsorbents,and looks forward to the research direction and application prospect of chitosan based adsorbents,in order to provide theoretical references for the preparation of chitosan-based dye adsorption materials with excellent performance and low price.

Key words: chitosan, dye, adsorption
