Импрегнированием гранул термически активированного доломита водными растворами сульфатов Fe(III) и Mn(II) с последующей термической обработкой получен Fe, Mn-оксидный катализатор. Методами дифференциально-термического анализа, дифракции рентгеновских лучей, низкотемпературной адсорбции-десорбции азота, сканирующей электронной микроскопии изучены его физико-химические свойства. Показана высокая эффективность окисления ионов Fe(II) в водных средах в каталитическом реакторе проточного типа, что обусловливает перспективность применения полученного катализатора для обезжелезивания артезианских вод.

A Fe, Mn-oxide catalyst was obtained by impregnation of thermally activated dolomite granules with aqueous solutions of Fe(III) and Mn(II) sulfates followed by heat treatment. Its physicochemical properties were studied using differential thermal analysis, X-ray diffraction, low-temperature adsorption-desorption of nitrogen, and scanning electron microscopy. The high efficiency of Fe(II) ion oxidation in aqueous media in a flow-type catalytic reactor was shown, which makes the obtained catalyst promising for the deironization of artesian waters.
