摘要
The method for determining concentrations of As, Sb, S, and Cu, Pb, Zn which are above 100 μg/g, within arsenic ore and stibium ore by inductively coupled plasma-atomic emission spectrometry (ICP-AES) with aqua regia digestion is reported in this paper. The experimental conditions such as placement time, solution acidity, and the influence of oxidant and complexing agents on As, Sb, S and the other elements were studied. No accurate data were obtained for Cu, Pb and Zn if the concentrations were lower than 100 μg/g, limited by the large dilution factor of 1 000. The accuracy and precision of the method were validated by reference materials.
