In the paper, the dissolution methods of such samples as steel and alloy are studied. Dissolve the samples with hydrochloric acid and nitric acid as well as the optimum instrument conditions of inductively coupled plasma mass spectrum (ICP-MS), select the spectral lines of elements to be tested with high sensitivity and fewer interferences as the analytical lines. The matrix matching is used to eliminate the influences of matrix effect in calibration curve so that the contents of lanthanum, cerium, praseodymium, neodymium and samarium in steel and alloys can be determined with the inductively coupled plasma source mass spectrometer.
