%X A method was developed to monitor triazines in surface water using the combination of solid phase extraction (SPE) and high performance liquid chromatography. Four different SPE cartridges were tested for extracting six triazines, including atrazine (A), simazine (S), prometryn (P), desethylatrazine (DEA), 2-hydroxyatrazine (OHA) and desisopropylatrazine (DIA), and finally ENVI-18 was selected as optimal. The method for solid phase extraction was further systematically studied for details. Optimal results of orthogonal design were determined as follows: pH 6, 5 mL methanol as eluting solvent, and no methanol added into water sample before extraction. The detection limits of six triazines were 0.14 microg/L for P, 0.12 microg/L for A, 0.08 microg/L for S, 0.08 microg/L for DEA, 0.10 microg/L for OHA and 0.18 microg/L for DIA. This method was applied for environmental aquatic samples, and the results showed that the concentration of prometryn in a lake was detected as (9.33 +/- 0.27) microg/L, as well as the concentrations of atrazine and prometryn in a river were detected as (5.28 +/- 0.43) microg/L and (7.12 +/- 0.54) microg/L respectively.
