| Abstract: | Seventeen rare earth and non-rare earth elements, Y, La, Ce, Pr, Nd, Gd, Tm, Dy, Lu, Ho, Er, Yb, Mo, Ni, Cu, Al and Fe in Mg-Y alloy have been determined simultaneously by ICP AES without preliminary separation. This method is simple and rapid with good reproducibility and high accuracy. |
