建立了一种以高效液相色谱(HPLC)测定果蔬中多菌灵残留的方法,该方法采用QuEChERS技术为前处理方法,以乙腈作为提取溶剂,以PSA(Primary Secondary Amine,N-丙基乙二胺)和C18填料作为净化材料。试验结果表明:多菌灵标准品在0.1～10.0mgL范围内线性相关系数为1.000;方法定量限为0.1mg/kg(S/N=10);加标浓度为0.5和5.0mg/L的平行5次测试结果相对标准偏差分别为2.98%和1.72%;0.1、0.5和5.0mg/L3个不同浓度的加标回收率在96%～110%之间。
A method was established for the determination of carbendazim residues in fruits and vegetables by high performance liquid chromatography (HPLC). The method used QuEChERS technology as the pretreatment method, acetonitrile as the extraction solvent, primary secondary amines (PSA) Diamine) and C18 filler as a purification material. The results showed that the linear correlation coefficient of carbendazim standard was 1.000 in the range of 0.1-10.0 mg / L; the limit of quantification was 0.1 mg / kg (S / N = 10); the spiked concentrations were 0.5 and 5.0 mg / L The relative standard deviations (RSDs) of the 5 parallel tests were 2.98% and 1.72%, respectively. The spiked recoveries of 0.1,0.5 and 5.0 mg / L at different concentrations ranged from 96% to 110%.
