Mnoho prvků v oceánských polymetalických uzlinách – Analýza fluorescenčním spektrometrem EDX9000B X

Použití energeticky disperzního rentgenového fluorescenčního spektrometru EDX9000B ke stanovení Na20 polymetalických nodulů, MgO styl, AI2O3, Si02, P2O5, SO3, Cl, K2O, CaO, TIO2, PROTI, Mn, Fe, spol, v, Cu and zinc, Tak jako, Sb, Rb, Y, Zr, Mo, Ba, La, Ce and powder direct tableting Pb27 kinds of components of the sample, the experience coefficient method and the Compton peak as the background of the peak/back ratio method to correct the absorption of elementsenhanced effect, with the international standard sample manganese nodules calibration equation (including spectral overlap correction) ve stejnou dobu, the method checked by standard material, has a good accuracy and can meet the ocean polymetallic nodules resources survey, evaluation Requirements. For primary and secondary and the vast majority of trace components, the method of relative standard deviation (RSD, n = 10) less than 5% compared with other methods of multielement analysis, sample preparation is simple rapid, and it is a kind of “zelená” “environmentally friendly” metoda.
