DETERMINATION OF TWENTY MAJOR, MINOR AND TRACE ELEMENTS IN SILICATE BY XRF SPECTROMETRY

An XRF spectrometric method has been developed for the determination o.f S, Na,Mg, Al, Si, P, K, Ca, Ti, V, Cr, Mn, Fe, Ba, Sr, Rb, Zr, Cu,Ni and Nb in different geological materials including silicate, clay, bauxite, ultrabasic rocks etc., with a fusion technique, in which a new mix flux of the Li2B4O7 and LiBO2 is used. Interelement absorption and enhancement effects are corrected by using the theoretical alpha coefficients and Rh Ka line Compton scattering radiation as internal standard. The precision and accuracy of the XRF method are excellent as compared with classical chemical method.
