摘要
测定了活性炭吸附铂和钯的热效应 :在盐酸溶液中为 - 4182 2和 - 12 80 6J/mol,在氰化钠溶液中为- 2 9116和 - 19470J/mol。测定了吸附等温线 ,其符合Freundlich等温式 ,吸附铂 :lgQ炭 =1 6 5 6 5lgc溶液 +2 142 1;吸附钯 :lgQ炭 =1 744 6lgc溶液 +2 12 6 6。研究了活性温度。
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.
