提出用溴甲酚绿作指示剂测定硫酸铵的分析方法。该方法用溴甲酚绿代替甲基红指示剂,可测定硫酸羟胺中硫酸铵的含量。本测定方法的相对标准偏差小于0.2%,加标回收率在99.52%～100.48%。
Proposed bromocresol green as an indicator for the determination of ammonium sulfate analysis. The method uses bromocresol green instead of methyl red indicator, and can determine the content of ammonium sulfate in hydroxylamine sulfate. The relative standard deviation of the determination method is less than 0.2%, the recovery of the standard addition is between 99.52% and 100.48%.
