Представлены результаты исследования адсорбционных свойств сшитых эпихлоргидрином хитозановых сфер. В ходе исследования была разработана методика получения и сшивки хитозановых сфер, а также магнитно-разделяемых композитов на их основе. Адсорбционная способность сшитых хитозановых сфер была исследована на примере водных растворов NiCl2 и K2Cr2O7 при варьировании концентрации ионов Ni2+ и Cr2О7 2- . Было показано, что адсорбционное равновесие в случае растворов хлорида никеля достигалось за 60 мин, тогда как в случае растворов бихромата калия требовалось более продолжительное время (420 мин и более). The paper presents the results of a study of the adsorption properties of epichlorohydrin-cross-linked chitosan spheres. During the study, a procedure was developed for obtaining and cross-linking of chitosan spheres, as well as chitosan-based magnetically separable composites. The adsorption capacity of cross-linked chitosan spheres was tested by the example of aqueous solutions of Ni2+ and Cr2O7 2- with different concentrations. It was shown that the adsorption equilibrium in the case of Ni2+ was achieved in 60 min, whereas in the case of Cr2O7 2- a longer time was required (420 min or more).
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
