| Abstract: | A method for the simultaneous determination of trace elements of lead, arsenic and cadmium in phosphate ores by inductively coupled plasma-atomic emission spectrometry (ICP-AES) was established. The detection limits of the method are 0.042 mg/L for lead, 0.053 mg/L for arsenic and 0.006 mg/L for cadmium. The recoveries of lead, arsenic and cadmium are 109.3%, 94.0% and 90.0% with precision (RSD,n = 11) of 0.86%, 1.36% and 1.08% respectively. The method has been applied to the routine inspection of lead, arsenic and cadmium in phosphate ores with satisfactory results. |
