Using Zr doped TiO2 nanotubes for the pre-concentration and sensitive determination of bisphenol A prior to fluorescence spectrometry in water samples

Abstract

The present study focused on the investigation of the applicability of a new material, Zr doped TiO2 nanotubes, used as the solid phase extraction adsorbent for the enrichment of bisphenol A. The possible impacting parameters on the extraction such as the kind and volume of eluent, sample pH, sample flow rate, and sample volume were investigated in detail. Under the optimal extraction conditions, the proposed method had excellent linear range of 1–80 μg L−1 and the LOD was 0.016 μg L−1. The relative standard deviation at the concentration of 20 μg L−1 (RSDs, n = 6) was 2.9%. Four different real water samples were used for validation, and the spiked recoveries were satisfactory in the range of 102.9–108.8%, and all these results indicated that Zr doped TiO2 nanotubes had much better extraction performance and would be widely used in the future.
