Zinc speciation and desorption kinetics in a mining waste

网页Mining waste typically has a high content of potentially toxic elements such as zinc (Zn), lead (Pb), and cadmium (Cd) that are usually found on the surface of soils after mining (Steinnes, 1995). Once mobilized in soils, these elements can be transferred to groundwater and plants, and present a potential threat to human health ( Sharma et al
