Online serviceThe stock solutions of Cu 2+, Cd 2+, Zn 2+, Pb 2+, and Ni 2+ were obtained by separately preparing a calculated mass of CuSO 4 ·5H 2 O, CdCl 2 ·H 2 O, Zn(NO 3) 2 ·6H 2 O, Pb(NO 3) 2, and NiSO 4 ·6H 2 O. This stock solution produced was again diluted with distilled water to obtain the relevant initial concentrations of to mmol/l.
Online serviceWhile distributions of Pb and Cu were similar, total concentration trended to decrease from 0 to 10 cm and increase at a depth of 10-20 cm, perhaps because Cd and Zn are more mobile than Pb and Cu. In smelter soil, the mineral content was high with low redox potential, and heavy metals will cause potential harm to the deep soil along with the ...
