Removal of lindane using electrokinetic soil flushing coupled with air stripping

Abstract This paper evaluates the remediation of soil spiked with lindane using a combined treatment consisting electrokinetic flushing (EKSF) air stripping to elucidate main processes occurring in when electric fields 0.75 V cm −1 and 1.50 are applied. The results demonstrate that is efficiently transported anodic cathodic wells fluids containing sodium dodecyl sulfate (SDS). Additionally, an important amount volatilized stripped injected air. In well, rapidly transformed into other species because strongly alkaline media. These also found portions next this confirming efficient transport chlorinated organics SDS. After 14 days operation, nearly 50% can be removed from soil. Operation large does not improve performance technology lower current intensities electro-osmotic fluxes higher evaporated water, despite water content matrix, indicating coexistence multiple inputs these processes.
