Voltammetric Determination of Cobalt and Nickel in Hard Magnetic Alloys

Abstract

A rapid, accurate, and extremely precise method for the simultaneous determination of nickel and cobalt in hard magnetic alloys using the techniques of voltammetry with continuously varying potential is described. The current-voltage curves in solutions containing pyridine and potassium chloride were obtained with an all-purpose voltammetric instrument based on analog computer amplifiers. The method was applied to the analysis of mixtures of cobalt and nickel in standard and unknown solutions. © 1961, American Chemical Society. All rights reserved.
