Physicochemical properties of sorbents based on silica gel modified by 1-phenylazo-2-naphtholic complexes of transition metals A. I. Makarycheva, Y. G. Slizhov

By: Makarycheva, Alexandra IContributor(s): Slizhov, Yuri GMaterial type: ArticleArticleSubject(s): газовая хроматография | хелатсодержащие сорбенты | полярность | хроматографические сорбентыGenre/Form: статьи в журналах Online resources: Click here to access online In: Russian journal of physical chemistry A Vol. 91, № 9. P. 1791-1796Abstract: Gas chromatography sorbents based on Silokhrom C80 and modified by 1-phenylazo-2-naphtholic complexes of 3d metals (Co(II), Ni(II), Cu(II)) are obtained. Their structural, chromatographic, and sorption characteristics are investigated. It is found that modifying them with 1-phenylazo-2-naphthols of transition metals has a considerable effect on the chromatographic polarity and selectivity of sorption materials. The prospects for the practical application of the obtained sorbents are demonstrated by experiments on the gas chromatographic separation of mixtures of different classes of organic compounds.
