Abstract:Treatment of synthetic oil refinery wastewater employing TiO2 assisted photocatalytic degradation (PCD) process was studied. Phenol was used as the model pollutant in all the experiments. Both UV light and TiO 2 were required for effective removal of phenol from the aqueous phase. For phenol-only studies, near complete phenol degradation was noted within 360 min. The removal of phenol in presence of oil, ammonia, lead, cyanide, sulfate, thiosulfate, and mercury was also studied in order to assess their effect on the phenol PCD. Presence of these species showed varying effects on the PCD trend of phenol. The presence of oil was generally noted to reduce the overall phenol removal from the contaminated water. Similarly, the time required for overall phenol PCD also increased in presence of both lead and thiosulfate. However opposite was noted for mercury. For mixed phenol and ammonia PCD systems at 10 and 5 ppm concentrations respectively, significant phenol removal was observed at pH 5, but with insignificant ammonia removal.
