Evaluation of the Immobilization of Coexisting Heavy Metal Ions of Pb²⁺, Cd²⁺ , and Zn²⁺ from Water by Dairy Manure-Derived Biochar: Performance and Reusability.

ABSTRACT: Heavy metals including Cd, Pb, and Zn are prevalent stormwater and groundwater contaminants derived from natural and human activities, and there is a lack of cost-effective treatment for their removal. Recently, biochar has been increasingly recognized as a promising low-cost sorbent that can be used to remediate heavy metal contaminated water. This study evaluates the immobilization/release performance of dairy manure-derived biochar (DM-BC) as a sustainable material for competitive removal of coexisting heavy metal ions from water and explains the underlying mechanism for regeneration/reusability of biochar. Results showed that the metal ions exhibited competitive removal in the order of Pb²⁺ ≫ Zn²⁺ > Cd²⁺. The pH played a decisive role in influencing met
