氢氧化钠中氯化钠含量测定方法的改进

The Improvement of the Measuring Method of the Content of Sodium Chloride inside Sodium Hydroxide

用硫酸铁铵代替硝酸铁来检测离子交换膜法氢氧化钠中氯化钠的含量 ,能简化分析步骤 ,缩短分析时间 ,同时可以保证分析数据的准确性。

Using ammonium iron sulphate to replace iron nitrate to check up the conent of sodium chloride inside sodium hydroxide produced by the way of ion exchange membrane can simplify the step of analyse and shorten the analyse time,also can assure the accuracy of analyse datas.
