Abstract:Summary Benzene was used as a probe to detect ·OH produced by photolysis of Fe(III)-pyruvate complexes in a homogeneous system. The Fe(III)-Pyr system was found to be not catalytic. Influence of pH, temperature, as well as the concentration of Fe(III) and pyruvate (Pyr) on the ·OH yield was investigated.
