Abstract : The aim of the work was to contribute to an understanding of the basic photochemical processes which lead to the evolution of oxygen from aqueous solutions. The research was divided into three parts: (1) the photochemistry of pure liquid water, when water itself absorbs the light below 2000A; (2) the evolution of oxygen from aqueous solutions of hydrogen peroxide under the influence of ferric ion catalysts (hydrogen peroxide is the halfway stage in the 4 electron equivalent change from water to molecular oxygen); (3) the photochemical evolution of oxygen from solutions containing ferric ions and hydrogen peroxide under the influence of light.
