| The concentrations of nine elements, including arsenic,antimony,bismuth,copper,zinc,magnesium,aluminum,iron and cadmium inleadconcentrate samplesweredeterminedby inductively coupled plasma opticalemission spectrometry(ICP-OES)after the samples were digested withmixtures of nitric acid, hydrochloric acid, hydrofluoric acid and perchloric acid.The measurement rangesfor As, Sb, Bi, Cu, Zn, Mg, Al, Fe and Cd were 0.01%-1.50%，0.01%-10.0%， 0.03%-5.00%，0.50%-10.0%，2.00%-10.0%，0.30%-2.00%，0.50%-3.00%，5.00%-12.0%and 0.030%-0.20%, respectively.The recoveries were 90%- 104%(n=3). This method is fast and simple, and was proved to be suitablefor simultaneous determination of As, Sb, Bi, Cu, Zn, Mg, Al, Fe and Cdin leadconcentrate samples. |
