VRB电解液的高锰酸钾电位滴定分析
Potassium permanganate based potentiometric titration of electrolyte of VRB
摘要
Abstract
The analysis of the state and the concentration of vanadium ions provided an important evidence for determining the state of charged vanadium ions, the capacity of battery and the charge-discharge efficiency. The potentiometric titration method was established to determine the vanadium electrolyte through KMnO4- (NH4)2Fe(SO4)2 system.The proposed method was used to analyze the single and mixed valence state of V(Ⅱ).V(Ⅲ),V(Ⅳ),V(Ⅴ) and total concentration of vanadium ions in electrolyte.The results showed that RSD (N = 5) based on the proposed method was no more than 3.67%.关键词
