| Abstract: | The adsorption heat of platinum and palladium with active carbon was determined,that are 41822, 12806 J/mol(in HCl solution) and 29 116, 19470 J/mol(in H_2SO_4 solution), respectively. The adsorption isothermal line with active c arbon was determined by experiment. It conforms with Freundlich adsorption isoth ermal equation that lg Q _C=1 6565 lg c _ s 2 1421 and lg Q _C=1 7446 lg c _ s 2 1266.The influence factors for activated temperature, ion intensity and pH were researched. |
