Removal of Cd, Pb, Cu and Zn from real contaminated soils with fresh and regenerated Na2EDTA
The leaching efficiencies using both fresh Na2EDTA and regenerated Na2EDTA on the remediation of contaminated soils from Chenzhou lead–zinc mining area located in southern Hunan Province (southern China) were investigated. The total concentrations of Cd, Pb, Cu and Zn in both contaminated soils exceeded the maximum permissible limits set by Ministry of Environmental Protection for soil. Under the ...
