| Abstract: | The method was established for the simultaneous determination of Nd,La,Ce,Sm,Dy,Gd,Co,Mn, Zr,B,Ga,Pr,Al and Cu in Nd-Fe-B alloy by inductively coupled plasma atomic emission speetrometry(ICP- AES).The effect of matrix and coexist elements on the determination are studied.By the use of efficient mathemati- cal mode MSF(Multi-component Spectral Fitting) and matrix match,complex background and direct spectral over- laps interferences were effectively eliminated,the RSD are less than 6%.The method is rapid and ... |
