PB(II) REMOVAL FROM KAOLINITE BY ELECTROKINETICS

In this study, the feasibility of using electrokinetics to remove Pb(II) from saturated kaolinite under controlled laboratory conditions was investigated. Pb(II) is selected since it is typical of heavy-metal contaminants in the environment. In light of the understanding developed for the creation of acid-base distributions in the process, this paper provides the results of the tests conducted for Pb(II) removal, presents an anslysis of the efficiency in removing Pb(II), evaluates the energy expenditure, and gives engineering implications for use of electrokinetic and remediation. It was found that the acid front generated at the anode in electro-osmosis flushes across the specimen, ultimately decreasing the pH of the effluent. These and other study findings are discussed. The study found that electrokinetic soil processing can be used efficiently to remove inorganic cations from soils and explains the fundamental underlying mechanisms by which the process occurs.
