Abstract

A method is presented for the determination of Cu(III) ion in semiconductor ceramic materials. It is based on (a) the reaction of copper(III) with Fe(II) ions, (b) the quantitative formation of Fe(III) ions, (c) liquid-liquid extraction of Fe(III) in the form of an ion associate between the FeCl4- anion with a Cationic Violet dye, and (d) spectrophotometric quantitation of the ion associate. All processes are executed in a single sequence of steps. The absorbance of the colored extracts obeys Beer's law in the range from 0.16 to 1.92 mg L-1 of Cu(III). The molar absorptivities range from 38,000 to 82,000 L mol-1 cm-1 depending on the kind of extractant used. The effects of other ions on the recovery of Cu(III) were studied, and those that generally occur with copper in semiconductor samples do not interfere.
