The calcium bentonite clays have a high capacity to bind metal ions dissolved in solution. This adsorption, the binding of chemicals to bentonite clay surfaces, is a rapid process and the binding is strong. Once these metals are bound to the bentonite clay they can be rapidly separated from water by removing the bentonite clay.
