本标准规定了无机化工产品中氯化物含量测定的通用方法--电位滴定法。本标准适用于氯离子含量在1mg/L~1500mg/L的试验溶液。分取用于滴定的试验溶液中氯化物(以Cl计)含量为0.01mg~75mg,当使用的硝酸银标准溶液浓度小于0.02mol/L时,滴定应在乙醇-水溶液中进行。
Scope
This standard specifies the general method for the determination of chloride content in inorganic chemical products - potentiometric titration. This standard applies to test solutions with a chloride ion content of 1 mg/L to 1500 mg/L. The content of chloride (calculated as Cl) in the test solution for titration is 0.01mg~75mg. When the concentration of silver nitrate standard solution used is less than 0.02mol/L, the titration should be carried out in ethanol-water solution.
