Based on acetylacetone a new organic reagent was synthesized. Its crystal structure was studied. Its complexation with copper was Studied by spectrophotometric method. The effect of the third component on the complexation of Cu-R was considered. The composition of the reactants was studied by different physico-chemical methods. The effect of foreign ions on complexation was studied. The technique was applied to the determination of trace amounts of copper in natural objects.
Аннотация. Синтезирован новый реагент-3-((Е)-2-гидроксибензилиден) гидразоно) индолин-2-он на основе салицилового альдегида. Определена его кристаллическая структура и спектрофотометрическим методом изучено комплексообразование этого реагента с железом (III). Исследовано взаимодействие железа (III) с 3-((Е)-2-гидроксибензилиден) гидразоно) индолин-2-оном в присутствии и отсутствии диантипирилметана (ДАМ), 8-оксихинолина, дифенилгуанидина (ДФГ). Разработанная методика применена для определения микроколичеств железа в банане, горохе и гречке. Ключевые слова: Спектрофотометрическое определение железа (III), комплексообразование, кристаллическое строение, диантипирилметан, 8-оксихинолин, дифенилгуанидин.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
