GF-AAS DETERMINATION OF TRACE AMOUNTS OF LEAD IN PHOSPHATE ORES
Conditions,including the fusion of sample and elimination of interferences caused by matirx effect,by the co-exsting ions and by the flow-rate of carrier gas for the GF-AAS determination of trace amounts of lead in phosphate ores were studied and optimized.In the application of the proposed method to the analysis of several phosphate ore samples,recoveries in the range of 90.5% to 107.0% were obtained.
