Abstract |
The effects of surfactants on the photochemical decomposition of selected pesticides are examined both in aqueous solution and on selected soil surfaces. Typical surfactants usually enhance the rate of pesticide photodecomposition. In solution, increased quantum efficiencies and increased overlap with available solar irradiation are observed. In addition, surfactants enhance the solubility of otherwise sparingly soluble pesticides. Photodecomposition on soil surfaces is inefficient. Surfactants enhance the rates of decomposition in certain cases on soil surfaces, but the effects do not appear to be sufficiently large to make such a mode of decomposition competitive. It has been postulated that the reason pesticide photochemistry on soils is so inefficient is that excitation energy is lost to pigments in the soil. |
