چکیده
|
This paper presents the results of the depollution of a kaolinite using the electrokinetical method. the electrokinetical process was applied on the sample for des duration equal to 48h,72h,96h,120h,168h and 192h. the results show that as function of time,the electrical intensity decreases and the potential difference increases. this behaviour is accompanied with a progressive diminution of the conductivity suggesting a migration of lead during the test. the electroosmotic flow is stabilized after duration equal to 168h. the measurements of the ph values after the tests show that the ph of the sample is acidic. for the acidic ph values,the lead is presented as free pb2+ and its elimination is easier than when it's present at other forms.
