Радиолиз жидкой пробы, помещенной в специально сконструированную в форме наковальни гидротермальную алмазную камеру, вызывает окисление Cr(III) до Cr(VI) при нагревании от комнатной температуры до 400oC и восстановление Cr(VI) до Cr(III) при 500oC. Наличие Cr(VI) в растворе подтверждается значениями двух подгоночных параметров, описывающих структуру спектров хрома у K-края полосы поглощения. </p></abstract><trans-abstract xml:lang="en"><p>Synchrotron X-ray radiolysis-induced redox in a chromium aqueous solution was monitored using in situ X-ray absorption spectroscopy. The radiolysis in the fluid sample within a specifically designed hydrothermal diamond anvil cell caused the oxidation of Cr(III) to Cr(VI) upon heating from room temperature to 400oC, and reduction of Cr(VI) to Cr(III) at 500oC. The two fitted components of the pre-edge features of the Cr K-edge spectra were used to identify the presence of Cr(VI) in the solution. </p></trans-abstract><kwd-group xml:lang="ru"><kwd>рентгеновская абсорбционная спектроскопия</kwd><kwd>хром</kwd><kwd>радиолиз</kwd><kwd>окислительно-восстановительный потенциал</kwd><kwd>supercritical fluid</kwd><kwd>X-ray absorption spectroscopy</kwd><kwd>chromium</kwd><kwd>radiolysis</kwd><kwd>redox</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">K.
