摘要：

Octadecyl (C18)-bonded porous silica was evaluated for the extraction of triazine and organophosphorus pesticides from natural water. The extraction results showed an effective performance when 1 1 of water was passed through small glass columns containing 500 mg of 50-100-mu-m C18 bonded porous silica. The adsorbed compounds were removed with ethyl acetate, evaporated to 200-mu-l and determined by gas chromatography. The overall average recoveries were greater than 85% except for dimethoate and trichlorfon. Application of this procedure to the analysis of natural water samples gave results that agree well with those obtained by solvent extraction methods.
