Abstract

Abstract : An amidoxime-modified chitosan, featuring favorable porosity and super-lipophilic properties, was successfully prepared for pigment red 224 enrichment. Abstract : A new amidoxime-modified material, firstly investigated for the treatment of dye wastewater, was synthesized by the copolymerization of N -(2-methyl-1-oxo-2-propen-1-yl)chitosan (MAc-CTS) and acrylonitrile (AN), and then amidoximation. A regeneration experiment with pigment red 224 showed that the adsorption capacity of the material for pigment red 224 is up to 315.79 mg g −1 at 10 °C with fewer than 10–15 oscillations. Also, the sorbent exhibited good reusability. The amidoxime-based polymer possess a potential application for the treatment of wastewater containing pigment red 224.
