USE OF CLEAN ENERGY TO REMEDIATE CONTAMINATED SOIL

Abstract

The aim of this laboratory study is to investigate the feasibility of using solar energy in combination with electro-kinetic remediation without enhancement conditions to remove cadmium from artificially contaminated soil. Two tests were performed to investigate the effect of applying continuous and constant voltage from DC power supply, and non-continuous and constant DC voltage from solar panel. The experiment was carried out in Baghdad city. The DC volte was generated by two Solar panel each one has a maximum voltage of (17 V). The experiments were commented in the mid of May 2016 (average length of daytime 14 h 3 min). The results showed that the use of solar energy in the present study to remove cadmium from contaminated soil is not successful because of the low removal efficiencies and the need for more time to substitute the stoppage of night times.
