【摘要】 利用高效液相色谱法测定葡萄酒中多菌灵残留量,样品以乙酸乙酯提取,二氯甲烷萃取净化,以ODS-C18柱(4.6mm×250mm,5μm)进行分析,流动相(V乙酸乙酯∶V乙酸铵=55∶45)流速为1mL/min时,多菌灵保留时间为7.016min,回收率为87.8%～107.5%,最低检出限为2×10-5mg/kg。更多还原

【Abstract】 The residual carbendazim in grape wine was measured by HPLC and the process was as follows:samples extracted by ethyl acetate,then extractive purification of the solution by methylene chloride,then the solution analyzed by ODS-C18 column(4.6 mm×250 mm,5 μm),mobile phase(V ethyl acetate∶V ammonium acetate=55∶45),flow velocity as 1 mL/min,retention time of carbendazim as 7.016 min,recovery rate as 87.8 %～107.5 %,and the minimum detection limit as 2×10-5 mg/kg.(Tran.by YUE Yang)更多还原
