摘要
研究了石墨炉原子吸收光谱法测定磷矿石中微量铅,探讨了熔样过程,基体效应,共存元素及载气流速等干扰,并进行了干扰抑制试验,提出了最优方式对磷矿石中微量铅进行测定,回收率为90．5％～107．0％。
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.
