   <abstract xml:lang="ru">
    <p>С помощью химической модификации ионами меди нового композитного материала на основе нановолокон оксида алюминия и наноалмазов в работе получен функционализированный композит нановолокна γ Al2O3 / наноалмазы / Cu2+ с улучшенными сенсорными свойствами для детекции фенолов в водной среде. Химическая модификация композита позволила более чем в два раза увеличить его каталитическую активность в реакции соокисления фенолов с &#13;
4-аминоантипирином в присутствии Н2О2. Полученный эффект позволил вдвое снизить порог минимально выявляемой концентрации аналитов при их тестировании с помощью функционализированного композита, что было продемонстрировано на примере детекции фенола и 4-хлорфенола. В работе показано, что полученный композит обеспечивает линейный отклик в широком диапазоне концентраций фенола (0,25–100 мкМ) и 4-хлорфенола (0,5–25 мкМ). Установлено, что адсорбированные на композит ионы Cu2+ прочно связны с его поверхностью, не десорбируются и не инактивируются реагентами реакции соокисления при многократном использовании композита. В модельных экспериментах показана применимость функционализированного композита в качестве многоразового сенсора в ходе последовательного многократного тестирования фенола в водных образцах. В работе также проведены сравнительные исследования кинетики и изотермы адсорбции ионов Cu2+ на композитный материал и матрицу из оксида алюминия, оценена их сорбционная емкость.</p>

   <trans-abstract xml:lang="en">
    <p>A functionalized composite γ-Al2O3 nanofibers / nanodiamond / Cu2+ with improved sensor properties for the detection of phenols in an aqueous medium was obtained by chemical modification with copper ions of a new composite material based on alumina nanofibers and nanodiamonds. The chemical modification of the composite made it possible to increase its catalytic activity more than twice in the co-oxidation of phenols with 4-aminoantipyrine in the presence of H2O2. The obtained effect enabled to reduce the threshold of the minimum detectable concentration of analytes by half when they were tested using a functionalized composite. What was demonstrated by the example of the detection of phenol and 4-chlorophenol. It was shown that the obtained composite provides a linear response in a wide range of concentrations of phenol (0.25–100 μM) and 4-chlorophenol (0.5–25 μM). It is found that the adsorbed Cu2+ ions are firmly bound to composite surface, are not desorbed, and are not inactivated by co-oxidation reagents during repeated use of the composite. The applicability of a functionalized composite as a reusable sensor was shown in model experiments in the course of sequential multiple testing of phenol in aqueous samples. Comparative studies of the kinetics and isotherms of adsorption of Cu2+ ions on a composite material and an alumina matrix, and estimation their sorption capacity were also carried out in the work.</p>
