| Abstract: | A rock sample in the RTFE autoclave is heated and dissolved with hydrochloric acid, nitric acid, fluorhydric acid and perchloric acid. The volatile component SiF 4 is saved. The regenerated precipitates of aluminum fluoride, calcium fluoride and magnesium fluoride are dissolved with heat boiling hydrochloric acid. The fluorous ions are combined sufficiently with saturated solution of boric acid. The sample solution is formed. Si, Fe, Al, Ca, Mg, K, Na, Mn, Ti and P in the solution are determined quickly and simultaneously by the plasma direct reading spectrometry. The method is accurate and reliable, which has already been applicated in the routine analysis. |
