Differential-pulse polarographic determination of iron in acids, waters, fruit juices and wines
Abstract
A method for the determination of iron by differential-pulse polarography, based on the formation of a 5,5-dimethylcyclohexane-1,2,3-trione 1,2-dioxime 3-thiosemicarbazone–iron(II) complex, is proposed. The method was applied to the determination of iron in acids, waters, wines and fruit juices.
