| Abstract: | The conditions of photocatalytic decomposition of organophosphorous compounds in semiconductor suspension have been studied. It was found that the simultaneous presence of light, photocatalyst and oxygen was necessary. The rates of photodecomposition of two organophosphorous compounds over various semiconductor catalysts were determinated, and the rates were depended on the kinds and surface properties of photocatalysts. The possible mechanism of the photodecomposition has been discussed. |
