Пробоподготовка состоит в обработке гидрофобных образцов ДМФА с последующим разбавлением полученных растворов водой. При использовании раствора меди в качестве внутреннего стандарта достигнута воспроизводимость результатов определения элементов методом РФА ПВО с Sr не более 0,05. Правильность определения Cs, Pb, Br и I подтверждена результатами определения методом ИСП-МС в растворах после обработки образцов ДМФА с последующим разбавлением 2 %-ной HNO3 для Cs, Pb, Br или гидроксидом тетраметиламмония (ТМАН) для Cs, Pb, Br и I. Правильность определения хлоридов подтверждена методом прямой потенциометрии в разбавленных растворах, при этом показано, что свинец не образует нерастворимых хлоридов в растворе ТМАН и не мешает определению. Влияние бромидов на определение хлоридов характеризуется потенциометрическим коэффициентом 10–3. Согласно полученным результатам определения элементов установлен химический состав синтезированных соединений — CsPbBr2Cl и CsPbBr2,7I0,3.</p></abstract><trans-abstract xml:lang="en"><p>An approach to TXRF determination of the composition of perovskite nanocomposites of the putative composition CsPbBr2Cl and CsPbBr2I is proposed. Sample preparation consists in treatment of hydrophobic samples with dimethylformamide (DMFA) and subsequent dilution of the obtained solutions with water. When using copper solution as an internal standard the reproducibility of the results of TXRF determination of the elements is attained with a Sr no more than 0.05. The validity of the determination of Cs, Pb, Br, and I is confirmed by the results of their determination by ICP-MS in solutions after processing samples in DMFA followed by dilution with 2% HNO3 for Cs, Pb, Br or tetramethylammonium hydroxide TMAH for Cs, Pb, Br, and I, whereas the determination of chlorides is confirmed by the method of direct potentiometry in diluted solutions. It is shown that lead does not form insoluble chlorides in TMAH solution and does not interfere with the determination. The effect of bromides on the determination of chlorides is characterized by a potentiometric coefficient of 10–3. The results obtained provide determination of the stoichiometry of the synthesized compounds CsPbBr2Cl and CsPbBr2.7I0.3.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>перовскиты</kwd><kwd>CsPbBr2X</kwd><kwd>рентгеновская флуоресценция с полным внешним отражением</kwd><kwd>РФА ПВО</kwd></kwd-group><kwd-group xml:lang="en"><kwd>perovskites</kwd><kwd>CsPbBr2X</kwd><kwd>total reflection X-ray fluorescence spectroscopy</kwd><kwd>TXRF</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">Zhao H., Zhou Y., Benetti D., et al.
