Abstract: The ionic liquid-immobilized expanded perlite (IL-EP) as a novel solid phase extraction adsorbent coupled with fluorescence spectroscopy for the separation/analysis of bisphenol A (BPA) was established. The results showed that BPA was rapidly adsorbed on IL-EP and separated/recycled from aqueous solution without centrifugation. It was worth mentioning that methanol as eluent could give a significant enhancement to the fluorescence of BPA. Moreover, the pseudo-second-order model fitted the adsorption kinetics data well, which indicated that chemisorption controlled the adsorption of BPA on IL-EP. The linear calibration curve for BPA was obtained over the concentration ranges of 0.01–10.0 μg mL−1 with the detection limits (LOD) of 0.3 ng mL−1. This method was applied to determinate BPA in food packaging material with reasonable results.
