摘　　要：采用氢化物发生原子荧光光谱法测定磷矿石中微量铅,研究了仪器工作条件、溶样介质、温度、酸度等对测定的影响以及Fe,Mg,Al,Ca等元素的干扰,加标回收率在91.2%～110.8%,获得了满意的结果。Determination of trace lead in phosphate rock is researched with the aid of hydride generation-atomic fluorimetry. Studied the instrument work conditions, medium, temperature, acid degree and the：interference of matrix Fe, Mg, Al, Ca, etc. Recovery test performed by standard addition method values in the range of 87.5%- 102.5%. The satisfactory results are obtained.
