Simultaneous determination of catalysts through a single catalytic kinetic run

Abstract

A method for the simultaneous determination of catalysts through a single kinetic run is proposed. It is based on the difference in the apparent orders p_i of the indicator reaction catalysed by each catalyst. The concentration of each catalyst can be deduced by multiple linear regression of the reaction rate v versus A^pi, where A is the concentration of the reactant, which changes with time. The Savitzky—Golay convolution method is used for calculating the reaction rate. As an example, Ru and Os have been determined on the basis of their catalytic effects on the indicator reaction between Ce^IV and As^III.
