自动电位滴定法测定氧化铁粉中氯离子的含量

Automatic Potentiometric Method for Determination of Chloride Ion in Iron Oxide Powder

研究了用自动电位滴定仪测定氧化铁粉中氯离子含量方法。试验确定了样品浸取酸度、时间和自动电位滴定仪参数等,建立了一种准确、快速测定氧化铁粉中氯离子含量的分析方法。方法的重现性和回收率都较理想。

The method for determination of chloride ion in iron oxide powder by automatic potentiometric titrator was studied. The sample leaching acidity and period, the parameters of the automatic potentiometric titrator and so on were determined in the tests. An analysis method for accurate and rapid determination of the chloride ion content in iron oxide powder was established. The reproducibility and recovery of the method were both close to the ideal.
