Abstract/OtherAbstract:
A simple visual titrimetric procedure is proposed for the catalytic determination of osmium, based on the arsenic(III)-bromate reaction. A detailed kinetic study of the catalytic reaction allows a mechanism to be proposed and optimum conditions for analysis to be selected. The analytical method has a detection limit of 10(-4) ppm osmium and possesses a higher degree of freedom from interference by ruthenium than other similar systems.
