摘要
提出将电导滴定装置与PC机联机测定钾盐中钾的含量,用专门编写的程序采集滴定数据和动态显示滴定曲线.这种联机方式可以提高分析结果的精密度,平行测定5次,其实验结果的变异系数≤0.1%.
By connecting a PC to an instrument for conductivity titration and by using a special program, the titrametric data can be acquired and the dynamic titration cure can be displayed. This method have been applied to assay of potassium salts. The method is simple, rapid and sensitive. The results are accurate.
