摘　　要：用有机滤膜采集空气中颗粒物样品,用HNO3—HCl—HClO4—EDTA微波络合消解后制成样品溶液。用石墨炉原子吸收分光光度法可确定样品溶液中锡的浓度。该方法具有消解完全,无损失,灵敏度高,准确度、精密度好等特点。Granule simples in air Collected with organic filter were made into sample solution by HNO3-HCl-HClO4-EDTAmicrowave digestion. The concentration of stannum in sample solution could be determine by GFAAS. The mothod had the characteristic of high sensitivity and accuracy, non-lose.
