摘　　要：测定焦磷酸盐镀铜溶液中柠檬酸铵含量时,剩余高锰酸钾直接用硫酸亚铁铵进行滴定。进行了共存元素的影响、酸度选择等条件试验。试验结果表明：方法的相对标准偏差均小0.80%（n=6）,加标回收率为99.87%-100.11%。此分析方法的精密度好、准确度高。Ammonium ferrous sulfate is used to titrate the remaining potassium permanganate when determinating ammonium citrate content in the pyrophosphate electroplating copper solution. The influence of coexisting elements as well as acidity were studied. The tests indicate that all the values of RSD＇S（ n = 6）are less than 0. 80% and values of standard addition recovery are in the range of 99. 87% to 100. 11%.This method has good precision and accuracy.
