摘要： 五氯硝基苯(PCNB)是一种含氯的杀菌剂,主要防治丝核菌引起的病害,广泛用于土壤处理和种子消毒,在蔬菜中 PCNB 的残留量为0.2 mg/kg,一般可用硫酸磺化——气相色谱法测定.本文利用硅镁吸附剂预处理柱对样品进行前处理,本法快速、简单,精密度高、准确度好,具有良好的实用性.

Abstract: The preconcentration of residual quintozene in vegetable with a solid phase extrac-tion column of Florisil and gas chromatographic determination was reported in this paper. This method is fast and efficient for residual quintozene analysis in vegetable.A 10% mix-ture of acetone-hexane was used as eluent that gave the best recoveries(92.0%～97.6%). The relative standard deviation is between 2.64%～6.07%.

Key words: quintozene, vegetable, gas chromatography
