title: Determination of traces of copper by the catalysed peroxodisulphate--bromide--ascorbic acid Landolt reaction.
abstract: The reaction between peroxodisulphate and bromide has been utilized for the catalytic determination of 0-1 ppm of copper in dissolved samples. The kinetics and mechanism of the uncatalysed and catalysed reaction have been studied, and the most important kinetic parameters determined. Under the experimental conditions described, the determination can be carried out in the presence of large numbers of other ions with an error less than 5%.
