Solar driven degradation of 4-chlorophenol

The feasibility of the Photo-Fenton reaction with sunlight as irradiation s ource was tested with model waste waters (4-chlorophenol) in different weat her conditions and at two sites. The degradation rate was found to decrease with rising length of path in experiments in a glass basin with a volume o f up to 201 in Vienna. In a compound parabolic collector (CPC) at the Plata forma Solar de Almeria increasing the amount of the iron catalyst proved to accelerate the degradation while the degradation rate decreased with risin g initial pollutant concentration.
