| Abstract: | An internal standard method by ICP-AES for quick determination of Cr, Ni, Cu and Mn in stainless steel has been developed. The measurment is carried out nitrohydrochloric acid to dissolve the sample and by using acidific water to dilute the sample. The concentration of HC1 and matrix in solution as well as selection of internal standard line are investigated. The optimal analytical condition is ascertained. The RSD are 2. 6—6. 3% and the recovery are 99—115%. The results of analysis for standard matters agree well with certified values. |
