| Abstract: |
| A new analytical method was proposed to simultaneously determine Cd, Co, Cu, Mg, Mn, Ni, Pb, Zn and Ca in laterite nickel ore by inductively coupled plasma atomic emission spectrometry (ICP-AES). The samples were first treated by hydrochloric acid, nitric acid and hydrofluoric acid and then determined by ICP-AES under optimal instrument conditions with hydrochloric acid as the testing medium. The detection limits for each element were 0～0.0033 μg/mL and the relative standard deviations （RSD，n=6）were 0.15%～6.95%. The recoveries for testing the spiked samples were between 91.4%～107.2%. The comparison test showed that the values determined by ICP-AES were consistent with those by flame atomic absorption spectrometry. |
