Abstract :
The aim of this investigation is to study Aniline (AN) omission in a laboratory system using TiO 2 Catalytic ozonation and pure ozonation method. The effect of key parameters such as PH was studied in three milieus of alkaline (with PH=9), Acidic (with PH=3) and neutral milieu (with PH=6.86) which is the same as solution PH. Moreover using Tio2 catalyzer by itself and along with ozonation was studied is examined with 0.012 and 0.007 values to determine Aniline degradation degree. Aniline concentration and absorbency degree was registered using UV spectrophotometry machine during experiment. Results obtained from this study indicated that Aniline degradation degree in pure ozonation and solution PH (which is the same as neutral milieu of P=6.68) is more than acidic and basic state and even more than in system combined with ozone and TiO2. Adding 0.012 gr and 0.007 gr of dioxide titanium nono particles whose degradation degree are 66.5% and 73% , respectively, have been reduced compared to pure ozonation. Degradation efficiency was obtained 85% in pure ozonation and neutral milieu
