【摘要】 采用双毛细管雾化器、氢化物火焰原子吸收测定砷、锑、铋、汞的方法比常规的火焰原子吸收法具有简便,快速、灵敏、成本低、效率高的优点.一次称样可以测定四个元素,文中用MGD标准样品证明了方法的可靠性。方法可应用于选矿产品以及地质组合样品中0.001％以上的砷、0.0001％以上的锑,铋和汞的测定.更多还原

【Abstract】 A hydride generation-flame atomic absorption spectrometric method for the determination of As, Sb, Bi and Hg in geological samples by using double capillary nebulizer is reported in this paper. No serious interferences are found and the method is suitable for the determination of the above mentioned elements in geological samples. The method is simple [and rapid, down to 0.001% As and 0.0001% of Sb, Bi, Hg can be determined. MGD standard samples have been analyzed,and the results obtained are in good agreement with the certificated values.更多还原
