Abstract

Изобретение относитс  к способу определени  меди (II), может быть использовано в химической промьшшенности и позвол ет повысить чувствительность и избирательность контрол . Смешивают раствор, содержащий 1 -10 моль меди,и фосфатньй буферный раствор с рН 5-8 и к смеси добавл ют раствор Sttc-f N-( 1-оксил-2,2, 6,6-тетраметилпиперидил-4 )-К-метилдитиокарбамато свинца (в качестве реагента ) в Ьоотношении медь:реагент, равном 1:1. Затем провод т экстрак .цию комплекса с последующей записью спектра ЭПР экстракта с эталоном tin The invention relates to a method for the determination of copper (II), can be used in the chemical industry and makes it possible to increase the sensitivity and selectivity of the control. A solution containing 1 to 10 mol of copper and a phosphate buffer solution with a pH of 5-8 are mixed and a solution of Sttc-f N- (1-oxyl-2,2, 6,6-tetramethylpiperidyl-4) -K- is added to the mixture. methyldithiocarbamato lead (as reagent) in copper: reagent ratio of 1: 1. Then the complex is extracted, followed by recording of the EPR spectrum of the extract with the reference tin.
