Application of magnetic N-doped carbon nanotubes in solid-phase extraction of trace bisphenols from fruit juices.
Food chemistry(2018)
Abstract
Magnetic N-doped carbon nanotubes were firstly applied as adsorbent in food analysis for pre-concentration of bisphenols in fruit juices followed by ultra-high performance liquid chromatography-tandem mass spectrometry determination. The magnetic nanoparticles were characterized by X-ray diffraction, infrared spectroscopy, scanning electron microscopy and vibrating sample magnetometer. The adsorption conditions were further optimized by response surface methodology. Under optimal conditions, the method provided good linearity with correlation coefficient (r ≥ 0.9979), excellent intermediate precisions (2.71-5.91%, n = 3), low limits of detection (LODs) ranging from 0.43 to 2.47 ng L-1, and satisfying recoveries of three juice samples (between 90.6% and 101%).
