тода Боэма для определения гидроксильных групп, содержащихся в нанотрубках в виде
аналогов фенольных групп, в карбокисильных группах, а также гидроксильных групп,
образующихся при гидролизе лактонных и ангидридных циклов. От известных методик,
где дегазация проводится путем длительного пропускания инертных газов (N2, Ar), пред-
лагаемая методика отличается способом удаления CO2 из реакционной системы в ваку-
уме и применением кондуктометрического метода определения точки эквивалентности,
что позволяет получать более воспроизводимые результаты при низких содержаниях
функциональных групп (n10-4 моль/г) в образцах углеродных нанотрубок.</p></abstract><trans-abstract xml:lang="en"><p>In this paper we propose a modified version of Boehm's titration method of determination of hydroxyl groups contained in nanotubes in the form of phenolic group analogues in carboxyl groups, as well as in hydroxyl groups formed as a result of the hydrolysis of lactone and anhydride cycles. The proposed method is different from the known techniques, where decontamination is carried out by a long pass of inert gases (N2, Ar), by its way of removing CO2 from the reaction system in vacuum and applying conductometric method for determining the equivalence point, which allows to obtain more reproducible results with low amounts of functional groups (n  10-4 mol / g) in samples of carbon nanotubes.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>титриметрия</kwd><kwd>кондуктометрия</kwd><kwd>потенциометрия</kwd><kwd>углеродные нанотрубки</kwd><kwd>поверхностные функциональные группы</kwd></kwd-group><kwd-group xml:lang="en"><kwd>titration analysis</kwd><kwd>conductometry</kwd><kwd>potentiometry</kwd><kwd>carbon nanotubes</kwd><kwd>surface functional groups</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Boehm H.P.
