Оксид магния находит широкое применение в качестве адсорбента, катализатора, идентификатора загрязняющих химических и токсических веществ, в процессах водо- и газоочистки. В настоящей работе методом осаждения, распылительного пиролиза и глицин-цитрат-нитратным методом синтезированы мезопористые порошки оксида магния, изучена их кристаллическая структура, микроструктура, гранулометрический состав и адсорбционные свойства. Определены наиболее оптимальные условия получения оксида магния глицин-цитрат-нитратным методом, которые позволяют получить порошок со средними размерами первичных частиц 12 нм и наименьшими размерами вторичных частиц – от 70 нм. Установлено влияние способа получения на адсорбционные свойства наноструктурированного порошка оксида магния. Высокие значения общего объема пор 1,038 см3 /г продемонстрировал порошок MgO, полученный методом осаждения.

Magnesium oxide is widely used as an adsorbent, catalyst, identifier of chemical and toxic pollutants, in water and gas purification processes. Mesoporous magnesium oxide powder has been synthesized by the method of deposition, spray pyrolysis and glycine-citrate-nitrate method, their crystal structure, microstructure, granulometric composition and adsorption properties have been studied. Optimal conditions for the production of magnesium oxide by the glycine-citrate-nitrate method have been determined, which make it possible to obtain a powder with average primary particle sizes of 12 nm and the smallest sizes of secondary particles starting from 70 nm. The influence of the method of obtaining nanostructured magnesium oxide powder on the physicochemical properties is established. High values of the total pore volume of 1.038 cm3 /g exhibited the MgO powder obtained by the precipitation method.
