BACKGROUND: In China, soil pollution is becoming more and more serious with the national economy rapidly developing. How to remedy soil containing heavy metals in an effective and low cost way is increasingly becoming an urgent problem. Utilization of renewable photovoltaic energy in the environmental protection field brings forward a solution. RESULTS: Cr(VI) removal from soil using an electrokinetic remediation process powered by photovoltaic solar modules and a DC-DC converter was studied. The results show that under solar irradiation intens...
