Tóm tắt

At present, the effluents of textile industry are severely contaminating to the enviroment, but the removal of pollutants from wastewater is rather costly because the synthetic nature of organic dyes. Many methods have been developed to remove the dyes from textile influents in practice, and it was found that chitosan, a marine polysaccharide, can be utilized as natural absorbents to absorbe and remove the dyes from textile wastewwater. The present study aiming to prepare the effective absorbents from chitosan, and improve their stability by radiation crosslinking to use as environmental friendly absorbents. The effects of chitosan concentration, content of crosslinking agent and radiation dose on chitosan beads were characterized. Absroption capacity of the resulting chitosan beads were also investigated with Direct Red 80.
