A method for determination of some triazine residues in water has been developed. The method involves concentration with C-18 solid-phase extraction cartridges followed by high-performance liquid chromatographic analysis using a C-18 column with UV detection at 230 nm, a mobile phase of methanol-water (60:40, v/v) at pH 4.6 (phosphoric acid) and a flow-rate of 0.8 ml/min. After optimization of the extraction and separation conditions, the method was validated. The method can be used for determination of atrazine, simazine, cyanazine and ametryn in water, within the international limits of 0.1 mu g/l. (C) 2000 Published by Elsevier Science B.V.
