| 摘 要： | 采用有机溶剂液液萃取的方式,以气相色谱-质谱联用仪负化学电离源法同时检测茶叶中氟乐灵、三唑酮和溴丙磷的残留量。茶叶加水浸泡后用丙酮：正己烷=1：1（V/V）的混合溶液高速均质提取,TPT柱净化后,用气相色谱-质谱联用仪进行测定和确认,外标法定量。该方法对茶叶中氟乐灵、三唑酮、溴丙磷的定量限均为0.01 mg/kg,方法在0.01-0.2mg/kg质量浓度范围内具有良好的线性关系。

| Abstract: | A gas chromatography-mass spectrometry method using negative chemical ionization（NCI） was presented for the determination of trifluralin,triadimefon and profenofos residues in tea.In the method,the tea sample was soaked by water and then extracted with acetone： hexane =1：1（V/V） mixed solvent twice,cleaned up on a TPT solid-phase extraction column.After purification,using gas chromatography-mass spectrometry for the determination and confirmation,and the quantification was performed by external standard method.The quantitation limit of this method is 0.01mg/kg for trifluralin,triadimefon and profenofos.The concentration exhibited a good linearity over the range of 0.01 to 0.2 mg/kg. |
