EDTA是一种重要的络合剂。EDTA用途很广,可用作彩色感光材料冲洗加工的漂白定影液,染色助剂,纤维处理助剂,化妆品添加剂,血液抗凝剂,洗涤剂,稳定剂,合成橡胶聚合引发剂,EDTA是螯合剂的代表性物质。能和碱金属、稀土元素和过渡金属等形成稳定的水溶性络合物。除钠盐外,还有铵盐及铁、镁、钙、铜、锰、锌、钴、铝等各种盐,这些盐各有不同的用途。此外EDTA也可用来使有害放射性金属从人体中迅速排泄起到解毒作用。也是水的处理剂。EDTA还是一种重要的指示剂,可是用来滴定金属镍,铜等 ,用的时候要与氨水一起使用,才能起指示剂的作用。
Ethylenediaminetetraacetic acid (EDTA) is an organic compound whose chemical formula is C10H16N2O8 and is a white powder at room temperature and pressure. It is a chelating agent that can combine with divalent metal ions such as Mg2+, Ca2+, Mn2+, Fe2+. Since most nucleases and some proteases require Mg2+, they are often used as inhibitors of nucleases and proteases; they can also be used to remove the inhibitory effect of heavy metal ions on enzymes.
EDTA is an important complexing agent. EDTA has a wide range of uses, and can be used as a bleaching and fixing solution for the processing of color photosensitive materials, dyeing auxiliaries, fiber processing auxiliaries, cosmetic additives, blood anticoagulants, detergents, stabilizers, synthetic rubber polymerization initiators, EDTA is a chelating agent. Representative substances of the mixture. It can form stable water-soluble complexes with alkali metals, rare earth elements and transition metals. In addition to sodium salts, there are ammonium salts and various salts of iron, magnesium, calcium, copper, manganese, zinc, cobalt, aluminum, etc., which have different uses. In addition, EDTA can also be used to rapidly excrete harmful radioactive metals from the human body for detoxification. It is also a water treatment agent. EDTA is also an important indicator, but it is used to titrate metal nickel, copper, etc., and it must be used together with ammonia water to function as an indicator.
