摘　　要：论述了采用自动电位滴定法和库仑法测定重整催化剂中氯含量,并介绍两种分析方法的基本原理和特点。考察了实验条件对测定结果的影响,如p H值、干扰离子、氯离子浓度等,并进行了精密度和加标回收率实验。结果表明,采用自动电位滴定仪和盐含量测定仪测定重整催化剂中的氯含量时,数据稳定性好,准确度高。The automatic potentiometric titration method and coulomb method were used to determine the chlorine content in reforming catalysts. The working principles and characteristics of the two methods were introduced. The influences of experimental conditions on measurement results were investigated, such as p H, interference ions and chloride ion concentration, and so on. Moreover, the experiments of precision and standard recovery rate were carried out. The results showed that the automatic potentiometric titrator and the salt content meter both exhibited excellent stability and high accuracy in the detection of chlorine content in reforming catalysts.
