Abstract :
The aim of this work was to examine photosensitized oxidation of 2-chlorophenol using solar light. Rose bengal,
methylene blue and chlorin e6 were used as sensitizers. They were immobilized in the silane gel and used in the form of a
thin film covering glass plates. In some lab-scale experiments xenon arc lamps were used as solar simulators.
The influence of various experimental conditions (light intensity, the amount of sensitizer, oxygen concentration) on
the rate of 2-chlorophenol degradation was investigated. The obtained results indicate a possibility of the application of
solar radiation in the middle latitudes for wastewater treatment. The use of silane gel as a carrier for the sensitizer
enables the pollutants elimination at a higher rate than in a homogenous system. The stability and durability of
immobilized sensitizers were also studied.
