Показано, что данные методы позволяют эффективно разделить компоненты водного раствора ЭГ + NaCl (KCl), что необходимо для газохроматографического определения ЭГ в указанных смесях. За счет гидрофобно-гидрофильных взаимодействий в системе ЭГ – вода – УНТ УНТ эффективно сорбируют ЭГ и практически не сорбируют хлорид калия. Коэффициенты разделения ЭГ и KCl на углеродных нанотрубках «Деалтом» лежат в интервале 7 – 15 (для 0,001 ≤≤ C0 ЭГ ≤ 0,1 и 0,001 ≤ C0 KCl ≤ 0,1 моль/дм3), степень извлечения ЭГ составляет 86 – 94 % при однократной экстракции, хлорид калия данными УНТ практически не сорбируется. Основой разделения ЭГ и солей щелочных металлов диализом с мозаичными мембранами является их высокая проницаемость для солей металлов и низкая проницаемость для ЭГ. За 4 ч диализа через мембрану АК-45 в NaCl-форме переносится 96 и 87 % NaCl (C0 = 0,001 и 0,01 моль/дм3 соответственно), для KCl-формы — 86 и 82 % KCl соответственно. За то же время диализа через мембрану АК-45 переносится менее 3 % ЭГ (C0 = 0,1 моль/дм3). Мозаичная мембрана АК-45 эффективно извлекает соли щелочных металлов из маломинерализованных водных растворов в отличие от традиционных ионообменных мембран, где данный перенос отсутствует вследствие явления Доннана. Коэффициенты разделения ЭГ и хлоридов щелочных металлов диализом с мембраной АК-45 лежат в интервале 13 – 38, что свидетельствует об эффективном разделении.</p></abstract><trans-abstract xml:lang="en"><p>A method for separation of ethylene glycol (EG) and alkali metal salts in aqueous solutions is developed using solid-phase extraction on carbon nanotubes (CNT) and dialysis with a domestic mosaic membrane AK-45. Both methods enable effective separation of the components of EG + NaCl (KCl) aqueous solution which is necessary for gas chromatographic determination of EG in the mixtures. Hydrophobic-hydrophilic interactions in the EG – water – CNT system provide efficient sorption of EG and almost zero sorption of potassium chloride by CNT. Coefficients of EG and KCl separation on Dealtom carbon nanotubes range within 7 – 15 (for 0.001 ≤ C0 EG ≤ 0.1, 0.001 ≤ C0 KCl ≤ 0.1 mol/liter), EG extraction rate is 86 – 94% for single extraction. CNT practically do not absorb potassium chloride. High and low permeability of mosaic membranes for metal salts EG, respectively, is a basis for separation of EG and alkali metal salts by dialysis. During a 4-hour dialysis, 96% and 87% of NaCl (C0 = 0.001 mol/dm3 and C0 = 0.01 mol/dm3, respectively), are transferred as NaCl through the AK-45 membrane (86% and 82% for KCl). At the same time an amount of less than 3% EG (C0 = 0 mol/dm3) is transferred during dialysis through AK-45 membrane. Mosaic membrane AK-45 appeared to be the most effective one regarding the transfer of alkali metal salts from low-mineralized aqueous solutions, unlike traditional ion-exchange membranes in the absebce of such transfer due to the Donnan phenomenon. Coefficients of alkali metal chloride and EG separation by dialysis with an AK-45 membrane range within 13 – 38, which indicates to their rather efficient separation.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>хлорид натрия</kwd><kwd>хлорид калия</kwd><kwd>этиленгликоль</kwd><kwd>мозаичные мембраны</kwd><kwd>разделение</kwd><kwd>углеродные нанотрубки</kwd><kwd>твердофазная экстракция</kwd><kwd>диализ</kwd></kwd-group><kwd-group xml:lang="en"><kwd>potassium chloride</kwd><kwd>sodium chloride</kwd><kwd>ethylene glycol</kwd><kwd>mosaic membranes</kwd><kwd>separation</kwd><kwd>carbon nanotubes</kwd><kwd>solid-phase extraction</kwd><kwd>dialysis</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">Mohammadi A.
