Abstract

The use of electrokinetic injection and transport for the distribution of an NAPLs-degrading microorganism in a sandy soil bed was studied. After the injection of the cell into cathode side of bed, an electric current was applied. The transport of cell though the sandy soil was achieved by electokinetics, mainly by electrophoresis, The pH control in electrode chamber plays un important role to achieve desirable cell transport because H$^{+}$ generated at anode is toxic or inhibits the transport of cells. Electokinetic distribution rate of bacterial cells changed depending on the applied electric current and pH. The degradation of diesel by electrokinetically transport cells were monitored.d.
