摘要: Sudan Red pollutants have gained more attention in recent years. The present study described a simple and sensitive determination method for with dispersive liquid-liquid microextraction coupled to high-performance liquid chromatography. Chlorobenzene ethanol were used as the extraction solvent disperser solvent, respectively. possible parameters such kind of solvents, ionic strength, sample pH that could affect enrichment been optimized. Under optimal conditions, well enriched linear ranges I II range 0.3-40 μg/L, III IV 1.2-160 μg/L. detection limits 0.18-0.46 precisions 3.7-5.9%. All these demonstrated proposed be good alternative routine analysis water samples.
