Partially calcined CaCO3 for remediating multi-heavy metals

Calcium carbonate (CaCO 3), a natural mineral abundant in the Earth's crust, is used for heavy metal precipitation because of its ease of handling and cost-effectiveness [8], [16], [23], [24]. CaCO 3 reacts with water to successively release calcium ions (Ca 2+ ) and carbonate ions (CO 3 2– ), consuming the hydrogen ions (H + ) and raising ...
