La, Ce, Pr, Nd, Ni, Co and Mn, in a rare earth hydrogen storage alloy (AB5 type) are determined by inductively coupled
plasma atomic emission spectrographic method. The analytical lines are selected by studying the spectrum overlap interference
of single elemental matrix. The matrix concentration being kept at 0.2 mg/ml, a matrix depression effect can be ignored. The
recovery ratios and relative standard deviations of this analytical method range from 82% to 129% and from 2.2% to 11.1%
respectively. A comparison of results between Inductively coupled plasma atomic emission spectrographic method and other
methods is satisfactory. This analytical method has such merits as high sensitivity, rapidity, accuracy and multi-element
simultaneous determination.
