Abstract

Dielectrophoresis (DEP) process could enhance the removal the Cd2+ and Pb2+ with less absorbent.

The removal rates of both Cd2+ and Pb2+ increased with the increase of voltage.

The overall removal rate of Cd2+ and Pb2+ in the binary system is higher than that of Cd2+ or Pb2+ in the single system.

DEP could cause considerable changes of the bentonite particles in both surface morphology and microstructure.
