The Sunlight Effect On Trace Pollutants In Wastewater, Alan R. Sheu
Theses
In order to study the sunlight effect on the degradation rate of trace pollutants, ortho-cresol was selected to serve as a model compound in our studies. Solution of ortho-cresol alone, methylene blue alone, and the mixture of ortho-cresol and methylene blue were exposed to sunlight for more than four hours and aliquots analyzed with a spectrophotometer in order to follow the changes in absorption. Rate data were obtained for these three cases as a function of pH.
The results indicate that methylene blue does catalyze the degradation of ortho-cresol in the presence of sunlight with lower pH's affording higher reaction …
