摘要
对EDTA配位滴定法测定Ni 2+的不同方法进行了实验比较,并从溶液配制、指示剂、缓冲溶液加入量等方面进行了深入讨论,完善和优化了EDTA测定Ni 2+的实验测定方法。
The determination methods of nickel by EDTA titration are compared experimentally. The effects of the preparation of standard solution , indicator used and the amount of buffer solution on added the analytical result are discussed , and then the modified method for Ni2 -＋-determination by EDTA titration is proposed.
