摘要
目前未出台关于自动电位滴定测碘的标准,为探讨此方法测碘的可行性,本文采用GB/T 13025.7-2012直接滴定法和自动电位滴定法分别对碘标准溶液和食盐中的碘含量进行测定。当样本量大,追求方便快捷时可使用自动电位滴定法测定。
At present,there is no standard for automatic potentiometric titration to measure iodine.In order to explore the feasibility of this method for measuring iodine,this paper used GB/T 13025.7-2012 direct titration method and automatic potentiometric titration method to measure iodine content in iodine standard solution and salt respectively.When the sample size is large and the pursuit of convenience and quickness,automatic potentiometric titration method can be used for determination.
