Using the hydrofluoric acid, perchloric acid decomposition, and perchloric acid, dissolution by aqua regia, the rare earth oxides in rocks and minerals were determined by plasma emission spectrum determination meth-od. The method had the advantages of high sensitivity, good recovery rate and the analysis of the characteristics of fast speed, and low cost, suitable for mass detection laboratory.
