摘要
The simultaneous determination of Ni, Al, P, Mg and Ca in nickel ores by inductively coupled plasma atomic emission spectrometry (ICP-AES) has been developed and is described in this paper. The precisions of Ni, Al, P, Mg and Ca were all less than 1% and the detection limits were 0.005 4 μg/mL, 0.002 8 μg/mL, 0.006 0 μg/mL, 0.003 0 μg/mL and 0.001 3 μg/mL, respectively. Compared with other methods,this method increased sensitivity and decreased the detection limit. It was applied to the determination of nickel ores from Indonesia, and the measured results were consistent with the standard values and RSD was below 1% (n=6).
