A hyper-cross linked polymer as an adsorbent for the extraction of chlorophenols
- 265 Downloads
A porous material (polytriphenylamine; PTPA) was synthesized by using triphenylamine as the monomer and dimethoxymethane as the cross-linker. PTPA was characterized by Fourier infrared spectrometry, X-ray diffraction measurements, scanning electron microscopy and N2 adsorption-desorption isotherms. The PTPA has a spherical-shape morphology and relatively high specific surface area. It is shown to be a viable adsorbent for solid phase extraction of 3-chlorophenol, 2,3-dichlorophenol, 2,4-dichlorophenol and 2,4.6-trichlorophenol prior to their determination by high performance liquid chromatography-mass spectrometry. Under the optimized conditions, recoveries from spiked samples are in the range from 92.5% to 106.3%. The limits of detection range from 0.03 to 0.3 ng mL−1 (at an S/N ratio of 3) in case of bottled juice, and from 0.03 to 0.1 ng g−1 in case of tomato samples. The enrichment factors for the four analytes are in the range of 127–183 for bottle juice, and from 110–150 for tomatos. Response is linear in the range of 1.0 to 40.0 ng mL−1 for juice, and 0.3–40.0 ng g−1 for tomatos. The relative standard deviations for the determination of the chlorophenols at 20 ng mL−1 in bottled beverage, and 20 ng g−1 in tomatos are lower than 5.7%.
