Pecsok和Samer研究了钼与EDTA络合物的特性和Lassner和Scharf提出钼的络合滴定法以来,这方面有了很大的发展.但绝大多数方法基于用硫酸肼把钼还元为五价,与EDTA形成深黄色的2:1络合物。由于络合物颜色较深,应用受到一定的限制。矢口裕彦、梶原武用盐酸羟胺作还原剂,钼(Ⅴ)与EDTA形成淡黄色的1:1络合物的新方法。Lassner等认为盐酸羟胺是络合剂,钼(Ⅵ)与羟胺、EDTA形成三元络合物。本
Pecsok and Samer studied the properties of complexes of molybdenum with EDTA and the great development has been made by Lassner and Scharf in the complexometric titration of molybdenum, but the vast majority of methods are based on the molybdenum reduction of five Valence, forming a dark yellow 2: 1 complex with EDTA. Due to the complex color darker, the application is subject to certain restrictions. Yaguchi Yahiko, Ebara Wu hydroxylamine hydrochloride as a reducing agent, molybdenum (V) and EDTA to form a light yellow 1: 1 complex method. Lassner, etc. that hydroxylamine hydrochloride is a complexing agent, molybdenum (VI) and hydroxylamine, EDTA ternary complex formation. this
