Предлагаемый метод основан на образовании окрашенного комплекса ионных пар ДЗ и указанных индикаторов путем экстрагирования их в хлороформ, при этом оптическую плотность измеряют при 411 и 415 нм соответственно. Экстракты интенсивно окрашены и очень стабильны при комнатной температуре. Молярная абсорбционная способность для ионных пар ДЗ-МО и ДЗ-БФС составляет 5.3х103 и 6.66х103 л/моль•см. Во всех случаях установлена стехиометрия реакции 1:1 и рассчитана условная константа устойчивости (Kf) комплексов. Оптимальный диапазон концентраций, определенный по графику Рингбома, составляет 16.67-50 мкг/мл. Предлагаемый метод успешно применен для анализа лекарственных форм. Помех со стороны обычных вспомогательных веществ, присутствующих в фармацевтических препаратах, не наблюдалось. Статистическое сравнение с использованием критерия Стьюдента, коэффициента дисперсии и F-критерия предлагаемого метода с методом ВЭЖХ показало их хорошее согласие.</p></abstract><trans-abstract xml:lang="en"><p>An extractive visible spectrophotometric procedure has been developed for diazepam (DZ) determination in pure and pharmaceutical forms using methyl orange (MO) and bromophenol blue (BPB) dyes. The proposed method was based on the formation of an ion-pair colored complex between diazepam and indicators via extracting them into chloroform whereby absorbance measured at 411 and 415 nm, respectively. The extracts are intensely colored and very stable at room temperature. The molar absorptivity for DZ-MO and DZ-BPB ion pairs were determined to be 5.3×103 and 6.66×103 L/mol • cm, respectively. The stoichiometry of the reaction was found to be 1:1 in all cases and the conditional stability constant (Kf) of the complexes was calculated. The effective range of concentration for an accurate determination as ascertained from Ringbom's plot was obtained at 16.67-50 μg/mL. The proposed method has been applied successfully to the analysis of drug dosage forms and no interference was observed from common excipients present in pharmaceutical formulations. The results obtained by the proposed method were statistically compared by means of the student t-test and by the variance ratio, and F-test with the HPLC method. Here it is shown to be in excellent agreement with the official method.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>диазепам</kwd><kwd>спектрофотометрия</kwd><kwd>метиловый оранжевый</kwd><kwd>бромфеноловый синий</kwd><kwd>комплексообразование ионных пар</kwd></kwd-group><kwd-group xml:lang="en"><kwd>diazepam</kwd><kwd>spectrophotometry</kwd><kwd>methyl orange</kwd><kwd>bromophenol blue</kwd><kwd>ion-pair complexation</kwd></kwd-group><funding-group><funding-statement xml:lang="en">Financial support from the research affairs of the university of Guilan is acknowledged.
