Disodium ethylenediaminetetraacetic acid, also known as EDTA 2Na, is a good coordination agent in chemistry. The chemical formula is C10H14N2Na208, with a molecular weight of 336.206. It has six coordination atoms and forms a complex called chelate. EDTA is often used in coordination titration to determine the content of metal ions. EDTA has important applications in industries such as dyes, food, and more.
application:
EDTA 2na is an important complexing agent and metal masking agent. It can be used in textile industry dyeing, water treatment, color photosensitive, medicine, daily chemical industry, papermaking and other industries, as an additive, activator, water purifier, metal ion shielding agent and activator in the styrene-butadiene rubber industry. In the dry-laid acrylic industry, it can offset metal interference and improve the color and brightness of the dyed fabric. It can also be used in liquid detergents to improve the washing quality and enhance the washing effect.
