It does not d sturb the natural env ronment dur ng remed at on and save energy at the same t me. In th s study, the mob l zat on and ts affect ng factors of 2, 4- d chlorophenol ( 2, 4- DCP) n sandy loam so l and l ght clay by non-un form electrok net cs was nvest gated, t hrough bench- scale exper ments, to assess the feas b l t y of us ng non-un form electrok net c technology to remed ate 2, 4-DCP-contam nated so ls. The results showed t hat non-un form electrok net c trans- port processes can effect vely st mulat e the desorpt on and movement of 2, 4- DCP n the t ested so ls, depend ng upon the so l charact er st cs, the elect rolys s react on on electrodes and the operat on mode. The movement of 2, 4-DCP n the sandy loam towards the anode was about 10 - 1 - 1 - 1 cmd under a potent al grad ent of 10 Vcm , about 10~ 15 cm
