Abstract

A new, simple, highly sensitive and rapid spectrophotometric method has been described for the determination of platinum(IV). The method is based on the oxidation of leuco xylene cyanol FF (LXCFF) to its blue form of xylene cyanol FF by platinum(IV) in sulfuric acid medium (pH 1.0--2.5), the formed dye shows an absorption maximum at 620 nm in acetate buffer medium (pH 3.0--4.5). The method obeys Beer's law over a concentration range of 0.3 to 2.6 µg mL--1 platinum, having molar absorptivity and Sandell's sensitivity of 5.1×104 L mol--1 cm--1 and 0.0038 µg cm--2, respectively. The optimum reaction conditions and other analytical parameters have been evaluated. The developed method has been successfully applied to the determination of platinum in pharmaceutical preparations, soil, natural water, plant material, platinum-containing catalyst, and synthetic alloy samples.
