摘要
在CuSO4-H2SO4 介质中 ,以次甲基兰为指示剂 ,借测量电解时所消耗的电量建立了定量测定铁的恒电流库仑分析新方法。该方法的准确度高 ,操作简单 ,对矿石的适应性好 ,应用于实际样品的测定 ,结果令人满意。
A new method,constant current coulometric analysis method is established for quantitative determination of iron content with methylene blue as an indicator by measuring the current consumption of electrolysis in CuSO4-H2SO4.The method is characterized by high accuracy and simple operation and is suitable for ore determination.The results of determination of actual samples by the method are satisfactory.
