| Abstract: | This paper introduced an analytical method for the determination of samarium in Pr-Nd mixture by ICP-AES.The Multicomponent Spectral Fitting(MSF) was adopted to eliminate serious spectrum interference.The samples are treated with HNO3(1+1) and the samarium is determined by ICP-AES.The detection limit for Sm is 9×10-8g,relative standard deviation is 1.0%~1.5%,It can be used for the determination of Sm 0.01%~1.00% in Pr-Nd mixture. |
