  • Phosphate-induced differences in stabilization efficiency

    Oct 25 2017 · The immobilization rate of Zn and Cd depends on pH and increased significantly in response to the excess phosphate application. This approach provides insight into phosphate-induced differences in stabilization efficiency in soils contaminated with multiple metals which is of theoretical and engineering significance.
