摘要
生物吸附重金属有广阔的应用前景。介绍了重金属生物吸附的配合反应、离子交换、无机微沉淀和氧化还原反应等机理,讨论了生物吸附热力学和动力学方程。阐述了影响生物吸附的pH值、共存离子、温度等主要因素,并对生物吸附重金属研究进行了展望。
Biosorption of heavy metal has wide applications. The mechanisms of heavy metal biosorption, including complexation, ion exchange, microprecipitation and oxidation reduction, are presented. Thermodynamics and dynamics of biosorption are also discussed. Key factors of influencing biosorption, such as pH values, coexistence ions and temperature are explained. The research directions are explored.
