摘要
将光谱纯试剂Sb_2O_3等添加到化探标样中配制六个锑矿标准,用20%Nb_2O5+80%Na_2B_4O_7稀释20倍以克服基体效应,对锑矿中14种元素进行同时测定。文中对稀释剂的选择进行了探讨。
An X-ray fluorescence method was described for determination of 14 elements in antimony ore. Six sythetic calibration standards were prepared from mixtures of spectrographically pure reagents (Sb2O3, CuO, ZnO, PbO, and As2O3)and available geochemical standard reference materials. Mulriple dilution and heavy diluents which consist of 80% Na2B4O7 and 20% Nb2O6 were used for matrix correction. A discussion was given on the selection of diluents.
