Pinto GM, Jardim IC: Use of solid-phase extraction and high-performance liquid chromatography for the determination of triazine residues in water: validation of the method. J Chromatogr A. 2000 Feb 11;869(1-2):463-9.
A method for determination of some triazine residues in water has been developed. The method involves concentration with C18 solid-phase extraction cartridges followed by high-performance liquid chromatographic analysis using a C18 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 microg/l. |
