Research on the Impact of Different VG on Electrokinetic Removal of Heavy Metal Wastes

Abstract:

This paper aims to investigate the effects of different VG (voltage gradient) on electrokinetic removal technology, and examine electrode pH, electric conductivity, voltage drop in the sample, electric current, and the electroosmotic flow. It is indicated that with the increase of VG, the electrolytic reaction rate accelerates during the electric removal experiment, which has affected both system current and the pH value & electric conductivity of electrolyte solutions. The higher VG is, the faster the electrolyte solution pH varies；the higher VG is, the faster the electric conductivity changes. Meanwhile the magnitude of electroosmotic flow increases with the increase of the VG.
