| Abstract: |
| The determination of content in Cobalt Content in Secondary battery wastes was studied by inductively coupled plasma atomic emission spectrometry(ICP AES).According to the selection principle of analytical lines, spectral line 201.153nm with little adopting and low sensitivity was selected as the analytical line. The instrument working conditions was chosen by the principle of best signal stability. The effect of acidand coexistence elements were discussed.This method has the advantages of speediness and simplicity,good accuracy and precision with 94.3%~104.6% recovery．The relative standard deviation(RSD)was below 1％．The method is suitable for the determination of Co in in Secondary battery wastes belowing 10% for daily analisis in industrial production. |
