Heavy Metal Precipitant
Heavy metal precipitants are chemical agents used in industrial wastewater treatment to selectively remove dissolved heavy metals such as copper, zinc, nickel, lead, cadmium, and chromium by precipitation as insoluble hydroxides, sulfides, or chelate complexes. They enable compliance with discharge limits for heavy metal ions. Products include sodium sulfide, trimercaptotriazine (TMT), and dithiocarbamate-based reagents.
