Abstract：Through the selection of spectral lines and filter for each element, and optimization of method, It is established that the working curve of each element. In this study, a rapid method was established for the rapid determination of 14 main components in rare earth hydrogen storage alloy samples including Mg, Al, Mn, Fe, Co, Ni, Cu, Zn, La, Ce, Pr, Nd, Sm and Y based on X-ray fluorescence spectrometry using filter paper. It is selected using plastic ring, adding 0.1 ml of the solution, slow filter paper, 40 mg/ml of the total solution concentration, to cover the sample with the tin sheet as the optimal condition. The relative standard deviation of 14 main components in 11 samples from a batch of samples is less than 2%. The rate of recovery of this method is between 92% and 106%. The method has better precision and accuracy, and can be used for the rapid determination of 14 main components in rare earth hydrogen storage alloy samples.
