In this paper, we characterize the leaching of heavy metals (Ni, Cu, Zn, Cd, and Pb) from eight contaminated soils over a wide range of pH (pH 0.4−12) using an original approach based on batch pH-static leaching experiments in combination with selective chemical extractions and geochemical modeling....
