Remediation of Cd Pb Cu and Zn contaminated soil using
The F2 fraction of Cd Pb Cu and Zn decreased when applying BM OS and BO which might promote the conversion of the combined form of heavy metals with Fe/Mn and CO 3 2 /HCO 3 to the form of hydroxide It was observed that the F2 fraction of Cd decreased by 35 at OS 3 treatment which might be due to the high pH of OS.

The Adsorption of Pb Zn Cu Ni and Cd by Modified Ligand in a
The 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 0.5 to 2.5 mmol/l.
