| 摘 要： | 研究了硅胶负载乙醇胺（SiO2-MEA）和二乙醇胺（SiO2-DEA）螯合吸附剂对Cu^2＋的静态饱和吸附量、吸附动力学、吸附热力学、动态吸附以及pH值对其吸附能力的影响．结果表明，SiO2-MEA和SiO2-DEA对Cu^2＋的静态饱和吸附量分别为0．2086，0．3082mmol／g；动力学和动态吸附过程符合Boyd方程，即为液膜扩散控制；热力学吸附过程符合Langmuir和Freundlich模型，即为单分子层吸附．

| Abstract: | The adsorption properties such as static adsorption capacities, adsorption kinetics, adsorption thermodynamics and dynamic adsorption of ethanolamine and diethanolamine supported on silica chelating resin to Cu^2＋ ions and the influence of pH value on adsorption properties were investigated. The results indicate that the static adsorption capacities of SiO2-MEA and SiO2-DEA is 0. 2086 and 0. 3082mmol/g, respectively; the adsorption kinetics and dynamic adsorption process followed G. E. Boyd equation, i.e. controlled by liquid film diffusion;adsorption thermodynamics process followed Langmuir and Freundlich model, i.e. unimolecular layer adsorption. |
