The method of analyzing rare earth elements by ICP- MS was dissolved with HCl- HNO3 -HF- H2SO4 in electric hot plate. Two internal standards of ^103Rh - ^187Re were selected to compensate the drift of analytical signals and correct matrix effects. The detection limit of each element was found to be 0.004 -0.019 μg/L. With an applicable dilution factor, the matrix effects were not observed. The results of analyzing standard materiel were satisfactory.
