主　　题：electrokinetic remediation cadmium kaolinite 

摘      要：Kaolinite from a lead-zinc mining district,which was spiked with cadmium,has been treated by electrokinetics to investigate effects of treatment time and applied voltage *** results showed that the increased test duration had induced a higher removal rate of *** treated for 7 days,cadmium was removed from kaolinite *** was also found that higher removal rate happened when a higher voltage gradient was applied and cadmium accumulated near the cathode because pH *** of pH near the cathode caused accumulation of ***,it was observed that cation exchange membrane which was placed between kaolinite and cathode could make pH lower than the initial value and avoid the higher pH near the *** a result,the high concentration accumulation of cadmium near the cathode was avoided.
