Modification of chitosan and application of its derivatives in water treatment were studied.Heavy metal ions,chemical oxygen demand,chroma and so on could be removed effectively by chitosan derivatives with no secondary pollution.Compared with the traditional chitosan derivatives,composite chitosan derivatives were more economic and efficient.It is significant to water treatment that better new chitosan ramifications will be synthesized,combined with other techniques and their treating effects for complex water.
