Remediation of cadmium, lead and zinc in contaminated soil with CETSA

The influence of washing solution concentration, pH and washing time on heavy metals removal was also investigated. The cadmium (Cd), lead (Pb), and zinc (Zn) removal efficiencies increased as washing solution concentrations increased from 0 to 60 g L −1, while they declined as pH increased from 3 to 8. Despite fluctuations between 90 …
