| 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. |
