Description

We have developed a method for the simulutaneous determination of 3 kinds of polar pesticides(methamidophos, acephate and trichlorfon)and 34 kinds of nonpolar pesticides(diazinon, chloroneb and simazine etc.)in water samples by means of solid-phase disk extraction and GC/MS.A SDB-XD Empore disk was set on a Carbon Empore disk, and a water sample of 500ml was simulutaneously passed through it.Pesticides extracted on the disk were simulutaneously eluted with 30ml of acetone/ethyl acetate(1:1)from the reverse side, which were obtained in good recoveries.The overall recoveries of polar and nonpolar pesticides from purified water over a concentration range of 0.0002 to 0.002mg/l were 73 to 109% and 70 to 120%, respectively.Their mean relative standard deviations were 2.4 to 9.8% and 1.3 to 19.4%, respectively.Similar results were achieved using river water.
