چکیده
An efficient method was developed for the synthesis of amino functionalized magnetic metal organic framework composite (Fe۳O۴-NH۲@MOF-۲۳۵) and the prepared composite was used as an adsorbent in magnetic solid-phase extraction (MSPE) for the separation and enrichment of Bisphenol A (BPA) from water samples followed by high performance liquid chromatography analysis. The prepared framework composite was characterized using transmission electron microscopy, x-ray diffraction, Fourier-transform infrared spectroscopy, Brunauer-Emmett-Teller and vibrating sample magnetometer techniques. Several parameters affecting the efficiency of magnetic separation including the amount of absorbent, extraction time, desorption solvent, and desorption volume were optimized. Under optimum conditions, the response of the method was linear over the concentration range of ۰.۱ to ۲۰ ng ml-۱ for studied BPA. The limit of detection of the method was ۰.۰۳ ng ml-۱ at a signal-to-noise ratio of ۳ with an RSD of lower than ۶.۵%. Finally, the proposed method was successfully applied for the determination of trace amounts of target analyte in mineral water samples.کلیدواژه ها

COI مخفف عبارت CIVILICA Object Identifier به معنی شناسه سیویلیکا برای اسناد است. COI کدی است که مطابق محل انتشار، به مقالات کنفرانسها و ژورنالهای داخل کشور به هنگام نمایه سازی بر روی پایگاه استنادی سیویلیکا اختصاص می یابد.
کد COI به مفهوم کد ملی اسناد نمایه شده در سیویلیکا است و کدی یکتا و ثابت است و به همین دلیل همواره قابلیت استناد و پیگیری دارد.
