摘　　要：目前大部分化工厂、炼厂等需测定石油产品中氯含量的相关单位,仍以微库仑法为主,因此提高微库仑法测定汽柴油中氯含量的准确性显得尤为重要,该文利用改变试验条件、优化电解池,数据对比等对影响汽柴油中氯含量测定的因素进行了分析改善,以达到提高氯含量测定准确性的目的。at present,most chemical plants,refineries and other relevant units that need to determine the chlorine content in petroleum products still focus on microcoulometry.Therefore,it is particularly important to improve the accuracy of microcoulometry in determining the chlorine content in gasoline and diesel.In this paper,the factors affecting the determination of chlorine content in gasoline and diesel are analyzed and improved by changing the test conditions,optimizing the electrolytic cell and data comparison,In order to improve the accuracy of chlorine content determination.
