摘要
采用氢化物－ＡＡＳ法测定了矿样和水样中的微量铅．研究了ＷＦ－Ⅱ型氢化物发生器与ＷＹＸ－４０１型原子吸收分光光度计联用，测定铅的最佳工作条件，提出了盐酸－硼氢化钠－铁氰化钾体系发生铅化氢．测得标样回收率为９５．６％～１０１．０％．变动系数为７．０５×１０￣（－２）％．
A simple and sensitive method for the determination of lead in water and mineral by WF-Ⅱ Hy-dride generation was improved.The improved system of hydragep chloride-potassium ferricyanide-sodium borohydide was adopted to evolve the hydride of lead and to determine micro amounts of Pb￣(2+) inwatet and mineral.The recoveries of standard samples are 95.6%,101.0%,The RSD are 7.05 ×10￣(-2)%.
