摘要
对水样中呋喃丹和甲萘威的高效液相色谱标准检测方法进行了改进,水样使用0.45 mm滤膜过滤后直接进样200μL,以甲醇∶乙腈∶水=20∶20∶60为流动相,流量为1 mL/min,采取等梯度淋洗,荧光检测器激发波长为330 nm,吸收波长为465 nm.改进方法对呋喃丹和甲萘威的加标回收率分别为87.5%~98.6%、89.3 %~105.2%,最低检出浓度分别为0.002 mg/L、0.001 mg/L,可用于水中呋喃丹和甲萘威的分析.
Improved the delection methods of Carbofuran and Carbaryl, directly in 200 μL water sample which had filter by 0.45 mm membrane. The mobile phase is methanohacetonitrile:water=20:20:60, 1 mL/min flow. The fluorescence detection Ex: 330 nm, Em: 465 nm. The recovery of carbofuran and carbaryl were 87.5 %-98.6 %, 89,3 %-105.2 %. The minimum detectable concentration were 0,002 mg/L, 0.001 mg/L.
