dc.description.abstractThe aim of this study was to optimize the dispersive liquid&#8211-
dc.description.abstractliquid microextraction (DLLME) parameters for simultaneous analysis through DLLME-gas chromatography&#8211-
dc.description.abstractmass spectrometry (GC&#8211-
dc.description.abstractMS) of six iodo-trihalomethanes, four haloacetonitriles, and one halonitromethane, which are residual disinfection products found in drinking water. Eleven disinfection by-product (DBPs) remaining in aqueous samples were extracted and concentrated using a simple, rapid, and environmentally friendly DLLME method, and then analyzed simultaneously by GC&#8211-
dc.description.abstractMS. The optimized DLLME parameters were a sample volume of 5&#8239-
dc.description.abstractmL, 100&#8239-
dc.description.abstractμL of dichloromethane as the extraction solvent, 1&#8239-
dc.description.abstractmL of methanol as the dispersion solvent, an extraction time of 60&#8239-
dc.description.abstracts, and 1.5&#8239-
dc.description.abstractg of sodium chloride for the salting out effect. The enrichment factor values obtained using the established DLLME-GC&#8211-
dc.description.abstractMS method were 19.8&#8211-
dc.description.abstract141.5, and the limit of detection and limit of quantification were 0.22&#8211-

dc.description.abstractμg/L and 0.75&#8211-
dc.description.abstract3.98&#8239-
dc.description.abstractμg/L, respectively. The calibration curves had correlation coefficients (r2) of 0.9958&#8211-
dc.description.abstract0.9992 in the concentration range of 0.5&#8211-
dc.description.abstract40&#8239-
dc.description.abstractμg/L, and they exhibited good linearity in quantitative analysis. This new method could be useful for analyzing eleven DBPs that remain in drinking water.-
