Green chemistry analytical method development: a revisit on the use of potassium ferrioxalate as a chemical actinometer

Abstract

The experimental details regarding the use of potassium ferrioxalate (3) as a chemical actinometer are discussed with respect to the precision, ruggedness and simplicity of the method. Despite the fact that as much as a ten-fold difference between the actinometer 3 quantum efficiency and the analyte quantum efficiency was observed, these differences were compensated for by the use of multiple actinometer solutions during the quantum yield determinations. As a tool in process development, the advantages of the merry-go-round apparatus for the evaluation of the influence of experimental conditions for the quantum yield of photochemical reactions are also discussed.
