本文提出以KNO_3、Ba(NO_3)_2、乙醇为底液,用库仑双点电位滴定法测定环境试样中的Cl~-。该方法测定Cl~-简便、快速,而且许多阴离子不干扰测定。
In this paper, the determination of Cl ~ - in environmental samples by coulometric potentiometry with KNO_3, Ba (NO_3) _2 and ethanol as base solution was proposed. The method for the determination of Cl ~ - is simple and fast, and many anions do not interfere with the determination.
