Abstract
A simple, sensitive procedure for extractive spectrophotometric determination of nickel has been developed. At pH 8.5, nickel reacts with purpurin (1,2,4-trihydroxyanthraquinone) to form a 1:1 red complex, extractable in methyl isobutyl ketone, with an absorption maximum at 525 nm. The characteristics of the complex, including optimum conditions of formation and extraction, and the adherence to Beer's law, are described. Nickel in cobalt and in iron and aluminum alloys has been determined by this method.
