摘 要: 用X射線熒光光譜測試了特種鋇玻璃中的Si， Al， Sr， Zr， Ba， Na和K七種元素。采用熔融法制樣，用人工標(biāo)樣作為校正標(biāo)準(zhǔn)，DRALPHA軟件計(jì)算理論α系數(shù)，C-Q方程校正元素間的吸收-增強(qiáng)效應(yīng)。結(jié)果表明，與經(jīng)驗(yàn)α系數(shù)校正法相比，理論α系數(shù)法的測定結(jié)果與化學(xué)分析法的測定結(jié)果更為一致。

Abstract:In order to correct matrix effect for determining Si,Al,Sr,Zr,Ba,Na and K in barium glass by X-ray fluorescence (XRF), the theoretical alpha coefficient method was used. In experiment glass samples were prepared by melting, artificial standard samples were used as standard for calibration, DRALPHA program was applied to calculate theoretical alpha coefficients, and C-Q equation was applied to correct the effect between elements. Compared with the empirical coefficient method, the results obtained from theoretical alpha coefficient method are more agreeable to those of chemical analyses.
Key words: X-ray fluorescence theoretical alpha coefficient barium glass
