摘 要:采用GDX-501吸附剂富集水中痕量丙溴磷,然后用气相色谱法直接测定,方法简便、准确、实用。水中丙溴磷的检出限为0.4 μg/L,低、中、高3种浓度的平均加标回收率为88.6%~99.3%,相对标准偏差在3.23%~4.%%范围内。
Abstract:A procedure for enriching profenofos from water with adsorbent GDX-501 is described. The eluate was separated and analyzed by gas chromatography with flame photometric detector. Detection limit of profenofos in water is 0.4 μg/L. Average recoveries of profenofos added in water are in the range of 88.6%~99.3%. The relative standard deviations are in the range of 3.2%~5.0%. This method is simple, accurate and precise.
