A method has been developed for carbofuran residues, based on coupling carbofuran (2,3-dihydro-2,2-dimethyl-7-benzofuranyl methyl carbamate) with diazotized aniline to form a yellow compound with an absorption maximum at 460 nm. The relationship between absorbance and concentration is linear for 1-10 mug carbofuran/5 ml. The method is sensitive and can be applied to the determination of levels as low as 0.025 ppm carbofuran in a 40 g crop or soil sample.
已开发出一种测定克百威残留量的方法，该方法基于克百威（2,3 - 二氢 - 2,2 - 二甲基 - 7 - 苯并呋喃基甲基氨基甲酸酯）与重氮化苯胺偶联，形成一种在460nm处有最大吸收的黄色化合物。对于1 - 10μg克百威/5ml，吸光度与浓度之间的关系呈线性。该方法灵敏，可用于测定40g作物或土壤样品中低至0.025ppm的克百威含量。
