| Abstract: | Inductively coupled plasma atomic emission spectrometry (ICP-AES) was used to establish a method for the determination of metal elements in the phosphoric acid. The experimental results indicated that when selecting the appropriate sample pretreatment way and optimal instrument operation conditions, the detection limits of this method could reach 0.0012 ug/g~0.0552ug/g with the recoveries between 95%~105%, which met the requirements of real sample analysis. |
