摘　　要：本文用弗罗里硅土富集水稻中的马拉硫磷 .用气相色谱法进行测定 ,方法简便、准确、实用 .检测限为 0 .5 μg/ kg.平均加标回收率为 94% ,平均相对标准偏差为 4.5 % .符合国家检测标准 .The enriching Malathion from vegetable and polluted water with adsorbent GDX-501 is described in this paper. The eluate was separated and analyzed by gas chromatography with flame photometric detector. Detection limit of Malathion in water is 0.5 μg/L. Average recoveries of Malathion added in water are in the range of 3.5%~6.0%. The method is simple, accurate and practical.
