EDTMP是一种有机多膦酸型的螯合剂,前人曾就它与Cu(Ⅱ)、Mn(Ⅱ)、Zn(Ⅱ)Co(Ⅱ)、Ni(Ⅱ)、Fe(Ⅲ)、Mg(Ⅱ)、Ca(Ⅱ)等金属离子形成螯合物的稳定常数,它本身的加合质子常数进行过测定和表征。文献报导用它作螫合剂进行配位滴定以测定铜,证明EDTMP与EDTA有相近的作用和效果。本研究工作的目的在于探
EDTMP is an organic polyphosphonic chelating agent. Previously, it has been reported that it is a chelating agent of organic polyphosphonic acids. Ⅱ), Ca (Ⅱ) and other metal ions to form chelates stability constants, its own additive proton constant were measured and characterized. It has been reported in the literature as a chelating agent for coordination titration to determine copper, which shows that EDTMP and EDTA have a similar effect and effect. The purpose of this research is exploration
