Abstract

The development and optimization of analytical methods for the better monitoring of disinfection by-products especially haloacetic acids in water are key step in order to estimate human exposure to such products after chlorination. A reliable and accurate analytical method is needed in order to reach the levels of concentration required by United States Environmental Protection Agency regulations. In this study a method was developed for determining halogenated acetic acids in drinking water, involving solid phase extraction, methylation derivatization, and GC-MS. The new SPE-GC-MS-SIM method is capable of analyzing all nine acids at extremely low μg L-1 level. Run time is significantly reduced without compromising analytical results. The major advantages of the method are the simplicity of the chromatography, short run time and low detection limits. The method performance, limits of detection and spiking recovery were evaluated and the results proved that the accuracy and precision were good. This method outperforms previous GC-MS methods especially for the determination of dibromoacetic, dibromochloroacetic, dichlorobromoacetic and tribromoacetic acids. The method has been used to analyse domestic tap water and water samples collected at a local water treatment plant.
