Ethylenediaminetetraacetic acid disodium salt

Among the EDTA salts, disodium salt is the most important. It is an important complexing agent. Used in electroless copper plating, gold plating, lead-tin alloy, electrochemical polishing of iron and steel parts and copper parts before silver plating solution, can also be replaced by EDTA-NA. Also used in detergent, liquid soap, shampoo, agricultural chemical sprays, color sensitive materials rinse processing bleaching fixing solution, water purifier, PH regulator, coagulant, etc. EDTA disodium, as a component of active agent, is mainly used for complexing ferrous ions and controlling the polymerization rate in the reduction initiation system used for styrene butadiene rubber polymerization.
