摘要：
This paper presented a method to determine potassium,sodium,calcium and magnesium in wet phosphoric acid.The phosphoric acid matrix was first removed by ion exchange resin.Then flame atomic absorption spectrometry was employed for final determination,eliminating the interferences from sample matrix.The proposed method is convenient,expeditious and practical,with highly precision and accuracy.The relative standard deviation is less than 3% while the recovery is 91.6%-103%.
