ResumoThe quantum yield of ferrous ion formation on irradiation at 313 nm is constant and has a value of 1.24 in the temperature range 5 – 80 °C. At temperatures above ambient the samples should be deoxygenated to eliminate reoxidation of Fe2+ by O2. At 80 °C there is a competing thermal reduction producing Fe2+ which is first order in ferrioxalate.
