摘　　要：利用Excel软件分析其金属离子在不同浓度下的终点滴定误差与过量EDTA的曲线关系 。The curve-line relation between the finishing-point error with different concentration condition and excessive volume of EDTA was analysed with the help of Excel Software in checking metal ions by reverse-titrimetric-analysis during coordinate chemical reaction. Based on that relation, the maximum concentration of measured ions and its corresponding maximum excessive volume of EDTA with the condition of certain permitted finshing-point error were determined.

关 键 词：配位反应 返滴定 试剂用量 终点滴定误差 过量EDTA 金属离子浓度
