摘要：
A method for the quantitative determination of the major constituents in laterites and bauxites by x-ray fluorescence using fused Na//2B//4O//7 glass discs is presented. The calibration curves were set up employing synthetic mixtures of oxides of Si, Al, Ti, and Fe. The interelement effects were corrected using a multiple regression analysis programed on a PDP 11/45 computer. The precision was determined by preparation and analysis of five synthetic pellets; the accuracy was ascertained by analysis of five international standards.
