title: Precise coulometric titration of precious metals-II. Determination of platinum(IV) with electrogenerated chlorocuprous ion in KClCuEDTA buffer medium.
abstract: A method for the precise coulometric titration of platinum(IV) with electrogenerated chlorocuprous ion in KClCuEDTA buffer medium is described. From 2.7 to 18.7 mg of platinum in pure platinum and platinum alloy are determined with standard deviations of less than or equal to 0.034% using potentiometric end point detection. The method has good accuracy and precision, selectivity and rapidity.
