Parker}, journal={Proceedings of the Royal Society of London. Series A. Mathematical and Physical Sciences}, year={1956}, volume={235}, pages={518 - 536} }
The earlier experiments with potassium ferrioxalate have been extended and a detailed study has been made of the photolysis of the acidified solutions previously recommended for chemical actinometry (Parker 1953). Accurate values of quantum efficiency have been determined at twelve wavelengths between 254 and 578 mμ, and the effect of temperature, light intensity and of photolyte composition have been investigated. At some wavelengths independent values of quantum efficiency have been obtained…

This alternative actinometry eliminates the postirradiation analytical procedure that needs phenanthroline as a complexation reagent for Fe2+ and the subsequent color development, and it enables the in-situ quantification of the light intensity in a simpler way by monitoring the formation of POM- as a proxy indicator.
