相对库仑滴定法

相对库仑滴定法是将库仑滴定仪器用于相对滴定法，以代替滴定剂，用消耗的电量代替滴定剂体积，它具有相对滴定法的所有特点，而且，由于没有滴定剂体积的稀释作用，便于离子强度的控制并使得滴定突跃增大，提高了方法的精度，实验结果表明，相对库仑滴定法用一地微量有机弱酸的测量具有很高的精度。

THE STUDY OF RELATIVE COULOMETRIC TITRITION

The relative coulometric titration is a new analytical method in which the coulometer is used instead of the titrant solution in relative titration and the volume of the titrant consumed in the titration is substituted by the amount of electricity. The new method possesses all the characteristics of the relative titration and has a higher accuracy and precision as compared with the general relative titration. Furthermore, the equivalent point break is enlarged and the ion strength of the solution keeps constant because the volume of the solution during the coulometric titration does not change. This method can be used to determine trace amount of organic weak acids with high precision and accuracy.
