浅析铝土矿烧失量的差异在X-射线荧光光谱分析中造成的影响刘静,马慧侠,彭展,白万里

本文探讨了一水铝土矿与三水铝土矿烧失量的差异在X-射线荧光光谱分析中造成的影响。采用试验的方式考察了硼酸锂熔融制样过程中铝土矿的烧失量损失情况；运用理论计算分析了烧失量的损失对测量结果的影响。试验与理论分析结果表明：当采用一水铝土矿绘制工作曲线来测量三水铝土矿样品时,将导致三水铝土矿中各组分测量结果偏高；烧失量的差异对主量元素测量结果影响较大,而对微量元素测量结果影响较小；待测物质的烧失量与基准物质烧失量差异越大,测量结果的偏差也就越大。

Brief analysisSof influence on different ignition loss of the bauxite in X- ray fluorescence spectrum analysis

The influence of different ignition loss of diaspore and gibbsite on the X- ray fluorescence spectrum analysis has been discussed in this paper. The experiment was executed to study the ignition loss of bauxite in the process of melted with lithium borate; the effect of ignition loss on the measurement results was analyzed by theoretical calculation. The experimental and theoretical analysis showed that: The measurement results of components would be higher when a curve which was established by diaspore that used to measured the sample of gibbsxite; the difference of burning loss had a great influence on the measurement dates of the main elements, but it had little influence on the results of trace elements; The greater measurement deviation would be achieved when the biggest difference appeared between the loss of the measured samples and the reference samples.
