The most often metal elements determined in soil and bottomset: Pb, Ce, La, Ba, Nb, Zr, Y, Sr, Rb, As, Zn, Cu, Ni, Co, Fe, Mn, Cr, V, Ti. The low limit of quantitative determination of this elements is about 0,001% (or 10 ppm).
Light elements: Ca, K, Cl, S, P, Si, Al, Mg, Na can be determined from 0,005% (Сa-Si), Al– 0,02%, Mg - 0,1%, Na - 2%.
The sample preparation consists of sample material drying and grinding to the particle size about 50 micron.
Grinded sample material is pressed in pellets, which are analyzed in a spectrometer according to the chosen program.
XRFA can determine total element content in a sample, as well as soluble forms of elements. In the latter case the sample material shall be treated with acid to dissolve unsolved compounds and then concentrated.
