| Abstract: | The fungicide Flutriafol was mineralised on irradiation of its aqueous solution, in which anatase P25 was suspended, with a medium pressure mercury lamp under an air stream. The half-time of reaction, t1/2, i.e. the time at which the total organic carbon of the solution was halved, decreased in the series of P25 loaded with RuO2>Pt>Ag>MnO2. Heating P25 at 500°C for 3 h reduced t1/2 compared to bare, unheated P25. |
