建立氟啶脲在甘蓝中的残留分析方法.样品用乙酸乙酯提取,弗罗里硅土柱净化,高效液相色谱法测定.结果表明:本方法最小检出量为1.2ng,在0.05、0.5、2mg/kg添加水平下,添加回收率在81.95%～100%范围内,变异系数范围为2.37%～6.21%.该方法符合农药残留分析的要求,适于甘蓝中氟啶脲的检测.
건립불정뇨재감람중적잔류분석방법.양품용을산을지제취,불라리규토주정화,고효액상색보법측정.결과표명:본방법최소검출량위1.2ng,재0.05、0.5、2mg/kg첨가수평하,첨가회수솔재81.95%～100%범위내,변이계수범위위2.37%～6.21%.해방법부합농약잔류분석적요구,괄우감람중불정뇨적검측.
A HPLC method was developed for the determination of chlorfluazuron residue in cabbage.Samples were extracted with ethyl acetate and cleaned up on Florisil column prior to HPLC analysis.The limit of detection of the method was 1.2 rig.At three spike levels(0.05,0,5,2 mg/kg),the recoveries of cldorfluazuron ranged from 81.95% to 100%,with coefficients of variation ranging from 2.37% to 6.21%.The figures of merit of this method can meet the requirements of pesticide residue analysis and therefore benefit its application in the determination of chlorfluazuron residue in cabbage.
