Review on Adsorption of Dye Wastewater by Modified Chitosan
Chitosan has abundant sources,large natural reserves,and a large number of amino,hydroxyl and other functional groups in the molecular structure,which has a good removal effect on dye wastewater.The stability,mechanical strength,adsorbability,separation and regeneration of the modified chitosan derived composite adsorption materials in industrial wastewater have been greatly enhanced.In this paper,the research progress of modification of chitosan and adsorption of cationic dyes at home and abroad was reviewed.
