Open publisher page 0 citations

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%.
