Phosphate-induced lead immobilization from different lead minerals in soils under varying pH conditions
This study investigated phosphate-induced lead immobilization from different Pb minerals in soils under varying pHs. Four soils were used, including one Pb-contaminated soil (NC-Soil) and three soils spiked with litharge (PbO), cerrusite (PbCO 3), or anglesite (PbSO 4), referred to as PbO-soil, PbCO...

3Cl]. Our results indicated that P addition can effectively transform various Pb minerals into insoluble chloropyromorphite in soils. This transformation was more significant at acidic condition (e.g., pH
≤

4 was the most effectively immobilized by P, followed by PbO and PbCO
