ICP-AES同时测定钼矿石中多种元素

Simultaneous Determination of Multielement in Molybdenum Ores by ICP-AES

采用碱熔酸化和ICP-AES同时测定钼矿石样品中Mo、SiO_2、P_2O_5、CaO、Fe_2O_3、S、Cu、Pb、Zn、Sn、As等多种元素,检出限分别为0.1μg/g、0.005%、0.03%、0.003%、0.001%、5μg/g、0.5μg/g、0.7μg/g、0.3μg/g、1.5μg/g、1μg/g;RSD为1.2%—3.8%。该法准确,快速,简便,结果令人满意。

The contents of Mo, SiO2, P2O5, CaO, Fe2O3, S, Cu, Pb, Zn, Sn, As in molybdenum ores were determined simultaneously by ICP-AES with alkali fusion, and acidulation. The detection limit for them are 0. 1μg/g, 0. 005%, 0. 03%, 0. 003%, 0. 001%, 5μg/g, 0. 5μg/g, 0. 7μg/g, 0.3μg/g, 1.5μg/g, 1μg/g,respectively. The RSD is in the range of 1.2%-3.8%. This method is accurate,quick and convenient, and the results are satisfactory.
