摘要：

An alternative photo electrochemical approach of potassium ferrioxalate actinometry has been investigated via the amperometric detection of product (Fe2+) formation at a glassy carbon electrode. The corresponding oxidation current response of [Fe2+] formed due to the photolysis of ferrioxalate, was monitored as a function of illumination time, which allowed the intensity of the illumination source to be determined. To validate this approach a parallel measurement to calculate the light flux was also carried out via monitoring the reactant (i.e. Fe3+) disappearance with photolysis time. (C) 2004 Elsevier B.V.
