Study on Reactive Dye Wastewater Treatment with Quaternary Chitosan

Abstract

Chitosan quaternary ammonium salt is synthesized by means of heterogeneous reaction, and then applied to treat reactive dye waste water. Effects of flocculation factors on treatment waste water are discussed. The results show that, the quaternary ammonium salt of chitosan concentration and settling time have great effects on the flocculation effect, and the stirring manner has little effect on flocculation.
