Abstract:A Xray fluorescence spectrometric method has been developed for the determination of Na, Mg, Al, Si, P, S, K, Ca, Ti, Cr, Mn, Fe and Ni in chromite with fusion sample preparation technique in which a mixed flux of Li2B4O7 and LiBO2 is used. The interelement effect is corrected by using the theoretical alpha coefficient. The method has been verified by the determination of these major and minor elements in standard reference materials. The results are in agreement with certified values with precision of 0.20% to 10.0% RSD(n=10). It is proved that the method is simple, rapid, costeffective and reliable.\=\=
Keywords:chromite  mixed flux  Xray fluorescence spectrometry  theoretical alpha coefficient\=\=
