中文摘要: 研究了环硫氯丙烷交联壳聚糖树脂对铂的吸附动力学、吸附热力学及解吸特性,并通过红外光谱法探讨了吸附机理.结果表明,吸附反应速率遵循一级速率方程,液膜扩散为控制步骤,吸附表观活化能为21.673 kJ/mol;其等温吸附符合Langmuir方程和Freundlich方程所描述的规律;在吸附过程中氨基和巯基参加了与铂的配位;吸附过程为自发的吸热吸附.

Abstract:Adsorption kinetics, thermodynamics and desorption of Platinum by chloromethylthiirane crosslinked chitosan resin were studied, and adsorption mechanism was also discussed through analyzing the FTIR. Results show that the adsorption speed rate followed the laws of the first-order kinetics model,liquid film diffusion is the control procedure, apparent energy of activation is 21. 673 kJ/mol, the isothermal adsorption followed the isothermal adsorption equations of Freundlich and Langmuir. In the process of the adsorption, amino and sulfhydyl of the resin attend the coordination with platinum; the adsorption process was an endothermic physisorption.
