Descrição: Published data on the efficiency of ultraviolet-radiation for the degradation of organic micropollutants in water are difficult to compare because of the diversity of photochemical reactors used and lack of data about the photonic fluxes of the UV light source. A method was developed for determining photonic fluxes at 253.7 nm emitted by low-pressure mercury vapour lamps and for evaluating the reflecting power of the internal wall of photochemical reactors, based on the photolysis of hydrogen peroxide in water. This approach had advantages over chemical actinometry using either potassium ferrixalate or uranyl oxalate salts. (English translation 325 pounds sterling, valid for 1990).
