A method is described for the analysis of aldicarb and its metabolites in urine by GC/FPD. The sample was concentrated with activated charcoal-Florisil column chromatography, eluted by dichloromethane-acetone (1:1v/v). The aldicarb, aldicarb sulfoxide in the eluted solution were oxidized by oxidizing reagent into aldicarb sulfone. The concentration of aldicarb sulfone was analyzed by GC/FPD. The detection limit of 0.0024 mg/L and coefficient of variation of 2.4%-7.4% were achieved. Mean recovery rates were 90.9%, 86.6%, 92.6% for aldicarb, aldicarb sulfoxide and aldicarb sulfone, respectively.
描述了一种用气相色谱/火焰光度检测器（GC/FPD）分析尿液中甲拌磷及其代谢物的方法。样品用活性炭-弗罗里硅土柱色谱法浓缩，用二氯甲烷-丙酮（1:1，v/v）洗脱。洗脱液中的甲拌磷、甲拌磷亚砜被氧化试剂氧化成甲拌磷砜。用GC/FPD分析甲拌磷砜的浓度。检测限为0.0024 mg/L，变异系数为2.4%-7.4%。甲拌磷、甲拌磷亚砜和甲拌磷砜的平均回收率分别为90.9%、86.6%、92.6%。
