- Abstract
Core-shell nanoparticles (NPs) of the type FeO@SiO were prepared, coated with 3 different ionic liquids, and tested for their capability of extracting bisphenol A (BPA). The results showed BPA is best extracted by NPs of the type FeO@SiO@[OMIM] (where OMIM stands for 1-octyl-3-methylimidazole hexafluorophosphate). Following desorption with methanol, BPA was quantified by HPLC with fluorescence detection in the UV. The following figures of merit were found under optimal conditions: A linear range from 0.5 to 2.0 × 104 μg·L‾, a detection limit of 90 ng·L‾, a relative standard deviation of 1.2 % (for n = 3 and 10 μg·L‾), and a pre-concentration factor of 25. The NPs can be re-used up to 10 times. The method was successfully applied to the determination of BPA in plastic tableware. [Figure not available: see fulltext.]
