用摩尔法和电位滴定法测定季铵盐含量，发现两种方法之间存在一个基本恒定的方法误差，摩尔法比电位滴定法的测定结果平均偏高3．90％，将此作为校正数值进行校正，其结果摩尔法与电位滴定基本一致，因此可用简便的摩尔法代替复杂费时的电位滴定法进行季铵盐含量的测定。
The quaternary ammonium content was determined by both the molar and potentiometric methods and found that there was a substantially constant method error between the two methods, with an average of 3.90% higher than the molar method potentiometric titration, as a correction value Calibration, the results of the molar method and potential titration are basically the same, so a simple molar method can be used in place of complex time-consuming potentiometric titration of quaternary ammonium salt content determination.
