▎ 摘　　要

The prospect of using nanostructured materials in sorption-desorption cycles is substantiated by their unique physical-chemical characteristics determining the performance properties of modern sorbents. Functional polymer compounds are increasingly being used as modifying additives to carbon matrices. The authors have developed a method for synthesizing an innovative nanocomposite based on 1,4-benzoquinone-modified graphene oxide. The product obtained is technically called ?polyhydroquinone/graphene oxide? (PHQ/GO). Technological parameters of the nanocomposite production were comprehensively studied. Quantitative dependences of the effect of the ratio of the initial components participating in the synthesis on the degree of GO surface modification were revealed. It was established that the amount of the modifier grafted nonlinearly depends on the weight of the initial monomer. This is presumably due to concurrent occurrence of several chemical reactions during the 1,4-benzoquinone polymerization. The physical-chemical characteristics of the material synthesized were investigated implementing the following techniques: scanning electron microscopy/energy dispersive X-ray spectroscopy, Raman spectroscopy, and thermogravimetry. The results of studying the structural, physical-chemical and operational properties of the nanostructured composite developed suggest that this material can be used as an efficient universal sorbent for the purification of aqueous media from different contaminants.
