环境介质中三唑磷(TAP)残留量低以及提取物组分过于复杂,样品需要经过富集和净化等前处理过程才能进行液相或气相检测.液-液萃取-气相色谱分析小麦地中土壤和秸秆中TAP含量分别达到0.973和1.865 mg·kg-1,气相色谱分析柑桔土水中TAP浓度在1—10μg·L-1[1],液-液微萃取和高效液相色谱分析水和果汁中的TAP残留浓度也取得较高的灵敏度[2].与液-液萃取相比,固相萃取(SPE)技术具有操作简便快速、有机溶剂用量少,且能去除一些杂质等优点.本
Environmental Triazophos (TAP) residues in the media are low and components of the extract are too complex for the sample to undergo liquid or gas phase pretreatment prior to enrichment and purification. Liquid-liquid Extraction - Gas Chromatography Soil TAP concentrations in soil and straw reached 0.973 and 1.865 mg · kg-1, respectively. The concentration of TAP in citrus soil was 1-10 μg · L-1 by gas chromatography [1], liquid-liquid microextraction and high performance liquid chromatography And TAP residual concentrations in fruit juices have also achieved higher sensitivity.2 Solid-phase extraction (SPE) has the advantages of simple and fast operation, less organic solvent usage, and the ability to remove some impurities than liquid-liquid extraction .this
