二乙撑三胺五乙酸(DTPA)是目前国际上新型的螯合剂,其对某些金属离子的螯合能力比一些传统螯合剂高出几倍至几十倍,被广泛用于化学工业、纺织印染工业、造纸工业和石油、冶金等领域。 由于DTPA生产工艺的复杂性,国内所用DTPA主要依赖进口,其价格昂贵,交货周期长,给这种新螯合剂的推广应用带来了极大的困难。河南省道纯化工技术有限公司和国内有关科研单位合作,
Diethylenetriaminepentaacetic acid (DTPA) is currently a new type of chelating agent in the world. Its chelating ability to some metal ions is several times to several times higher than that of some traditional chelating agents and is widely used in the chemical industry, Textile printing and dyeing industry, paper industry and petroleum, metallurgy and other fields. Due to the complexity of DTPA production process, DTPA used in China mainly relies on imports, which is expensive and has long delivery cycle, which brings great difficulties to the popularization and application of this new chelating agent.
