Determination of the main element in brine by energy dispersive X-ray fluorescence spectrometer Compass4294

The application scheme established a set of energy dispersive X-ray fluorescence spectrometer Compass4294 method for the determination of main elements of sulfur chloride potassium calcium in brine. The results show that the method is suitable for the test and analysis of high salinity brine, and a certain concentration of Mg has no obvious influence on the determination results. The analytical precision (RSD,n=15) of the method was 1.57%-5.25%6, and the detection limits were S 0.0050 g/L, C1 0.0035 g/L, K0.0050 g/L and Ca 0.0012 g/L. The results of S. Cl and K in brine were in good agreement with those of gravimetry, titration and atomic absorption spectrometry.
