壳聚糖及其衍生物处理工业废水的研究进展

Progress of the Application of Chitosan in the Disposal of Industrial Wastewater

综述了近年来壳聚糖及其衍生物在处理工业废水中的应用。壳聚糖及其衍生物可处理工业废水中的重金属离子,如Cr(Ⅵ)、Cu(Ⅱ)和Zn(Ⅱ)等;可处理含染料的工业废水,如处理直接紫B、直接绿BE以及甲基橙等染料;还可用于处理印染、造纸和含油废水。壳聚糖及其衍生物具有易分离、可生物降解,无污染等特点,是绿色的水处理剂,且我国壳聚糖资源极为丰富,探索其在工业废水处理中的应用有着重要的价值。

The recent applications of chitosan and their derivatives in industrial wastewater treatment were reviewed. The application of chitosan in treatment of industrial wastewater which contained heavy metal ions such as Cr（VI）, Cu（ II ） and Zn（ II ）, and which contained dyes such as Direct Violet, Direct Green BE and methyl orange, and in treatment of dyeing wastewater, papermaking wastewater and oil wastewater was introduced. Chitosan had the advantages of the easy separation, biodegradation, non-pollution. And chitosan was a green water treatment agent and rich in China. So it was valuable to explore the application of chitosan in treatment of industrial wastewater.
