REMEDIATION OF HEAVY METAL CONTAMINATED SOIL BY ASYMMETRICAL ALTERNATING CURRENT ELECTROCHEMISTRY
Xu, J., C. Liu, P.-C. Hsu, J. Zhao, T. Wu, J. Tang, K. Liu, and Y. Cui.
Nature Communications 10:2440(2019)

This study presents a remediation method design and demonstration using asymmetrical alternating current electrochemistry to achieve high degrees of contaminant removal for copper, lead, and cadmium at different initial concentrations (from 100 to 10,000 ppm). Soils reached regulatory levels for a residential scenario within a reasonable treatment time (from 30 min to 6 h). Excessive nutrient loss in treated soil was not observed, and no secondary toxic products were produced. https://www.nature.com/articles/s41467-019-10472-x.pdf
