壳聚糖及其衍生物对重金属离子吸附性能的影响

摘要

The research progress on effects of chitosan and its derivatives of adsorption of heavy metals were introduced.The influencing factors of adsorption such as pH,temperature,time,concentration of solution and coexistence substance were discussed.The thermodynamic and kinetic equation of the adsorption process was also discussed.Development trend of adsorption of heavy metals by chitosan and its derivatives were proposed.%介绍了采用壳聚糖及其衍生物吸附处理废水中重金属离子的研究现状,探讨了pH、温度、吸附时间、溶液初始浓度和共存物质等因素对壳聚糖及其衍生物吸附重金属离子的影响,分析了吸附过程的热力学和动力学方程.展望了壳聚糖及其衍生物吸附重金属离子的发展趋势和应用前景.
