| Popis: | In order to develop an online detection method for polycyclic aromatic hydrocarbons (PAHs) in honey, graphene oxide-functionalized mesoporous silica was prepared and introduced as the coating in the field of in-tube solid-phase microextraction. An extraction tube was coupled to high performance liquid chromatography with diode array detector, and the online analytical system was constructed. After the main extraction and desorption conditions were optimized, a sensitive and online method based on matrix-matched calibration was established towards trace PAHs in honey. The method exhibited wide linear range from 0.8 ng g−1 to 250 ng g−1 and low detection limit of 0.25 ng g−1, and the enrichment effect reached 2719. The proposed method was validated and successfully applied to the analysis of six honey samples. The extraction tube showed good durability and acceptable chemical stability during the experiment. |
