【摘要】 建立了二氯甲烷提取、高效毛细管柱分离、气相色谱-氮磷检测器测定水中呋喃丹的方法。优化了试验条件,以HP-5和HP-1301双柱定性,方法在0.00 mg/L~1.00 mg/L之间线性良好,检出限为2.0×10-5mg/L,RSD≤6.5%,加标回收率为93.6%~110%。更多还原

【Abstract】 A method was established for determination of carbofunan in water samples which extracted with dichloromethane,separated by fused silica capillary column and detected with GC-NPD.The experiment condition was optimized and the compound decided by double capillary columns HP-5 and HP-1301.The linear relation was excellent between instrument responds and calibration standard ranges both from 0.00 mg/L to 1.00 mg/L.The limits of detection in water sample were 2.0×10-5 mg/L.The relative standard deviation was within 6.5%,and the recovery was from 93.6% to 110%.更多还原
