A gas chromatographic-mass spectrometric method was developed for the determination of pesticides in compost. The investigated pesticides included two fungicides, two herbicides and 10 insecticides. The pesticides were extracted from the compost by pressurized liquid extraction. The extract was cleaned up by a partition between hexane and acetonitrile followed by a dispersive solid-phase extraction using a porous carbon made from Moso bamboo (Phyllostachys pubescens). The overall recoveries were 81-104% and the relative standard deviations (RSDs) ranged from 2.4 to 12%. The minimum detectable concentrations were 0.02-0.04 microg g(-1). This method was successfully applied to a compost sample from food waste as well as commercial compost.
建立了一种气相色谱 - 质谱法用于测定堆肥中的农药。所研究的农药包括两种杀菌剂、两种除草剂和10种杀虫剂。通过加压液体萃取从堆肥中提取农药。提取物先通过正己烷和乙腈分配进行净化，然后使用毛竹（Phyllostachys pubescens）制成的多孔碳进行分散固相萃取。总体回收率为81 - 104%，相对标准偏差（RSDs）为2.4%至12%。最低检测浓度为0.02 - 0.04 μg g⁻¹。该方法成功应用于食物垃圾堆肥样品以及商业堆肥。
