谢德华 %A 施周 %A 陈世洋 %J 环境工程学报 %D 2012 %I %X Dynamic and thermodynamic phenomenon of the cation membrane exchanging of copper ion was studied.It was found that when the temperature was 25℃ and pH of the solution was 6,the exchange capacity of ion-exchange membrane for Cu2+ was 0.506 mmol/g.The ion exchange rate increased with increasing of the initial concentration of copper ion,or temperature and stirring speed.Ion exchange process has a good results fitted with a reaction rate equation.△G0<0 indicated that the ion exchange reaction can occur spontaneously.△H0m>0 indicated that exchange reaction was endothermic.△S0>0 indicates that exchange reaction was an entropy increased reaction. %K cation exchange membrane %K copper ion %K dynamics %K thermodynamics
