ABSTRACT

In this study, bio-electrokinetics was used to increase migration of arsenic by activating endemic microorganisms in the soil. In this technology, bio-electrokinetics which the cultured soil microorganisms and nutrients injected combines with biological technology. This technology using electrical movement of microorganisms could overcome the weakness of late degradation speed and low removal efficiency. And, various soil microorganisms reduce ferreous, manganese, etc., using organic matter by as an electron donor by injecting mixture of soil microorganisms and nutrients instead of using electrolyte of the electrode. Accordingly, surrounding metal oxide microorganisms convert arsenic (III) to arsenic (V) to increase migration of arsenic (III), in consequence, migration of arsenic increased in 60 to 70% compared to about 30% of conventional electrokinetics.
