Исследование состояния производных 8-оксихинолина в водных растворах

Abstract

The different forms of derivatives 8-oksihinolina, containing the substituent in orto-position to functional group, in water solutions are investigated at different рН. Introduction of the substituent leads to strengthening of acidity and increase of reagents' selectivity at reaction with ions of metals. A perspective photometric reagent can be 2 (5N-tetrazolil-5)-8-oksihinolin, not reacting with the majority of transitive metals, but forming with ions of nickel and iron (II) strong complexes of structure 1:1.

Изучено состояние производных 8-оксихинолина, содержащих заместитель в ортоположении к функциональной группе, в водных растворах при разных рН. Введение заместителя приводит к усилению кислотности и повышению селективности реагентов при комплексообразовании с ионами металлов. Перспективным фотометрическим реагентом может быть 2-(5Н-тетразолил-5)-8-оксихинолин, не реагирующий с большинством переходных металлов, но образующий с ионами никеля и железа(II) прочные комплексы состава 1:1.
