二甲基甲酰胺(DMF)中的NaBH4混合、并反应,在有机相中产生SbH3,导入石英炉中进行原子荧光测定。方法检出限和精密度分别为0.54ng/mL和4.9%,分析结果与标准物质推荐值相吻合。<em><Abstrcat>A new method for atomic fluorescence spectrometric determination of trace antimony by flow injection online extraction combined with hydride generation in organic phase was established. Antimony was extracted into tributyl phosphate, and reacted with sodium tetrahydroborate to form antimony hydride in N,Ndimethyl formamide. The antimoug hydride was then determined by atomic fluorescence spectrometry. The detection limit of the method was 0.54 ng/ml and relative standard deviation was 4.9 %.</em></p><p class='subject'><strong>关 键 词：</strong><a
