【摘要】 选用安捷伦7890A-FPD,DB-1701(30 m×0.25 mm×0.25μm)毛细管色谱柱分离,样品用乙腈提取,氮吹水浴浓缩温度为70℃,建立了14种有机磷农药在绿色食品蔬菜黄瓜中的残留分析方法。结果表明:14种农药在0.01～1.0 mg/kg范围内线性良好,相关系数为0.9978～0.9998,在23min内能够完全分离;14种有机磷农药的回收率均在65%～120%范围内,其相对标准偏差均低于5%,以3倍信噪比计算出的检出限均低于日本肯定列表限量要求。该方法适用于绿色食品蔬菜中14种有机磷农残的同时检测。更多还原

【Abstract】 Selected Agilent 7890A-FPD,DB-1701(30 m×0.25 mm×0.25 um)capillary column,extracted with acetonitrile, concentration temperature was 70℃with nitrogen blow.An analytical method for the determination of organ phosphorus in cucumber of green vegetables by using gas chromatography was established.The results showed that the 14 organ phosphorus’s linearity were good,their correlation coefficient were from 0.9978 to 0.9998 in range 0.01～1.0 mg/kg and they could be separated within the 23 min;At the same time that the 14 organ phosphorus’s recovery were from 65%to 120%,and RSD%less than 5%,detection limit less than limits of Japanese Positive List System.The conclusion was that this method was suitable for detecting 14 organ phosphorus in cucumber of green vegetables at the same time.更多还原
