A method for the simultaneous determination of 11 triazine herbicides residues in river water has been developed. It involves solid-phase extraction (SPE) pretreatment step and rapid resolution liquid chromatography-tandem mass spectrometry (RRLC-MS-MS). In the SPE pretreatment step, the adsorptive performance of MWCNTs material as SPE adsorbent and the elution capability of five kinds of solvents were investigated; in the LC separation step, a rapid resolution high throughput LC column, was used and the gradient elution mode adopted. The linear correlation coefficients (r (2)) of the method for 11 target analytes varied between 0.9930 and 0.9980, the mean recoveries were in the range of 73.0 and 98.0% with relative standard deviations (RSD) 2.6 similar to 4.2%, the method detection limits (MDL) were all below 0.1 ng L-1. An expanded uncertainty of not more than 20% was estimated for each analyte at the spiked concentration of 4.0 mu g L-1. The proposed method was applied to the determination of the residue concentrations of 11 pollutants in Songhuajiang River water.
