Facile preparation of aluminum nanocomposites and the utilization in analyzing BPA in urine samples

Abstract Self-produced peanut shell AC (activated carbon) and Al(OH)3 (aluminum hydroxide) were successfully synthesized by ultrasound with CTAB (cetyltrimethyl ammonium bromide), and both new nanocomposite ACAl(OH)3@CTAB were evaluated as adsorbents for absorption of BPA (Bisphenol A) and utilized for the determination of BPA in urine by high-performance liquid chromatography coupled with fluorescence detector. Then the AC and AC@Al(OH)3@CTAB nanocomposites were examined by X-ray diffraction spectra, infrared spectrum, scanning electron microscope, transmission electron microscope, X-ray photoelectron spectroscopy techniques and differential pulse voltammetry analysis. The extraction elements such as adsorption pH, time, dose, desorption solvent, elution method were also discussed. Under the optimized extraction condition, the recovery of BPA in urine sample can achieve to 99.5% when using AC@Al(OH)3@CTAB as the SPE (solid-phase extraction) absorbents. For the methodological analysis, the linearity was detected in the range of 0.2–50 ng $ mL^{−1} $ (R2=0.999 3), and the limit of detection can be 0.05 ng $ mL^{−1} $. Within-day and between-day relative standard deviations were less than 3.7 and 5.2%, respectively. The synthesized new nanocomposite (AC@Al(OH)3@CTAB) showed excellent absorptive capacity, and the proposed SPE-HPLC-FLD methodology was proved to be efficient, sensitive and operable when using AC@Al(OH)3@CTAB as absorbents for BPA detection in complicated biological samples..
