摘要：

A comparison of three analytical procedures for the determination of lindane, p,p'-DDT and methoxychlor in water suspension during their photocatalytic oxidation in the laboratory photochemical reactor was performed. Analysis of the pesticides was carried out by: liquid-liquid extraction, direct aqueous injection, and solid phase microextraction using gas chromatography with electron capture detector, flame ionisation detector, and mass selective detector. Liquid-liquid extraction has given the best results because of good accuracy, precision, good recoveries of pesticides and the possibility to determine pesticides and their by-products in aqueous suspension.
