铷和铯含量的示波极谱滴定法测定

Determination of Rubidium and Cesium by Oscillographic Titration

用了示波极谱滴定法测定硝酸盐样品中铷和铯的含量，回收率为９７７８％～１００３％，相对标准偏差均值为０２１％。该法以示波极谱图形突变来确定滴定终点，终点直观，不受溶液颜色、沉淀的影响，具有准、快、简、省的特点。

Rubidium and Cesium in sample of nitrate were determined by oscillographic titration.The end point,being indicated by a sudden change of oscillogram,was not affected by the color of the solution and the precipitation.The recoveries ranged from 97 78% to 100 3% with a RSD of 0 21%.The proposed method proved accurate,precise and simple.
