Abstract: The efficiency of soil remediation techniques generally depends upon the contaminant sorption by soil and contaminant desorption from soil. Sorption and desorption again depends upon the soil contaminant interaction. Generally the desorption of heavy metals from fine grained soils like clay is considered as lengthy and costly process, particularly under in-situ conditions. In this research acoustically enhanced column tests were performed to evaluate the influence of acoustics to desorb heavy metal contaminant like zinc from fine grained soils like clay, considering in-situ stress conditions. The test results show that the sorption of zinc remained significantly higher than that of desorption, application of acoustics increased the removal of zinc ions sorbed on solid phase of soil and optimum increase in effluent concentration achieved at 1.4 pore volume.
