| Abstract: | The best testing conditions are determined according to the study on the testing method of P2O5, Al2O3, CaO, MgO, Fe2O3, Cd in P ore. The element recovery 95.3%- 105.4%, relative standard deviation （n = 12） 2. 53% -5.80%, limit of detection 0. 5ppm -7. 86ppm. The results are satisfactory according to the analysis examination of several state standard materials and ore samples. |
