Metalsorbents are metal precipitating agents for water and wastewater applications in municipality and industrial operations. Metalsorbents are a range of sulfur based chemical precipitants (anionic) that readily bond with metals in their dissociated forms (cationic), forming an insoluble compound that readily precipitates, and is subsequently removed from the treated stream through settling or filtering. In order to decrease production of potentially toxic gases, sulfur is chemically bonded to an organic molecule, forming dithiocarbamate. Various grades are available corresponding to various organic substrates. Metalsorbents are efficient in removing a wide array of complex or chelated metals, including copper, zinc, chromate, silver, cadmium, lead, mercury, cobalt, and nickel.
