Abstract本发明涉及一种钒电池正极电解液浓度的紫外定量测定方法及其应用,通过对V(IV)钒化合物酸性溶液做全谱扫描,确定其特征吸收峰并绘制标准曲线,以测定钒电池正极电解液中V(IV)的浓度;再通过向V(V)钒化合物酸性溶液中加入过量还原剂,对反应产物做全谱扫描,确定其特征吸收峰并绘制标准曲线,以测定钒电池正极电解液中总钒浓度,扣除V(IV)的浓度,即得V(V)浓度。还原剂能将V(V)全部还原为V(IV),而不含其它价态,剩余还原剂能将还原产物V(IV)全部络合或完全不络合。本发明测定结果准确、操作过程简单、便捷,可用于钒电池正极电解液浓度的测定、含有V(V)或V(IV)钒离子相关产品的实验室及工业分析和...
