The optimized method requires 38μL of the water-soluble ionic liquid 1-butyl-3-methylimidazolium chloride, and 5mL of seawater or industrial effluent. After appropriate work-up, a drop (~10μL) of an ionic liquid is formed that contains the analytes of interest. It is diluted with acetonitrile and injected into the HPLC system. This procedure is accomplished without heating or cooling the solutions. The method is characterized by (a) average relative recoveries of 90.2%, (b) enrichment factors ranging from 140 to 989, and (c) precisions (expressed as relative standard deviations) of less than 11% when using a spiking level of 10ngmL−1. The limits of detection range from 0.8ngmL−1 for 4-cumylphenol to 4.8ngmL−1 for bisphenol-A.
