摘要 本文利用锌在示波图形上有敏锐切口并可指示滴定终点的性质。采用EDTA连续络合滴定V、Sn和Al。回收率均为99.8~100.1%。相对标准偏差均小于0.048%。用于测定范围在0.5%以上的合金及钢样时,结果令人满意。 A very simple procedure has been developed for the consecutive complexometric titration of V,Sn and Al. In a buffer solution of pH5. 8 the zinc incision is used to indicate the end point of titration. The relative standard deviations are all less than 0. 048% and the recoveries of V,Sn and Al are in the range of 99. 80~100. 1%.
