Abstract:The sample was dissolved in 3 ml hydrochloric acid and 1 ml nitric acid, and La408.672 nm and Ce 456.236 nm were selected as the analytical lines. A method for the determination of trace lanthanum and cerium in rare earth steel by inductively coupled plasma optical emission spectrometry (ICP-OES) was established. The results show that the calibration curve of each element has good linearity, the correlation coefficient can reach 0.99999, and the determination range is 0.0001% ~ 0.10%. The detection limit was 0.00002% for La and 0.00006% for Ce. The relative standard deviation (RSD) (n = 8) of lanthanum and cerium in standard samples were 2.18% and 1.68% respectively.
