摘要: The application of photocatalysis in the treatment organic micropollutants wastewater is an interesting alternative and object a great interest over last years by many researchers. stage adsorption micropollutant on photocatalyst, mainly titanium oxide anatase form, determining process photodegradation. We present experimental study phenol, chosen as model pollutant, (Degussa P25). measure quantity phenol adsorbed was made UV spectroscopy. equilibrium reached after 1 h; kinetics were slow obeyed Lagergrein model. chimisorption monolayer Langmuir survey also showed that there advantage to operate at velocity agitation natural pH. ultrasonic drives light increase (5%) because this mode reduces phenomenon agglomeration particles therefore increases interfacial area catalyst.
