Özet
The aim of this study was to use non-modified nano titanium dioxide (TiO2 ) material to develop the sonocatalytic decolorization of Methylene blue (MB) and Reactive Red 198 (RR198) in aqueous solu-tions. The study is highlighted by the pHpzc value of nano TiO2 . Electrostatic attraction or repulsion can occur due to anionic (RR198) and cationic (MB) dyes. The maximum sonocatalytic decoloriza-tion efficiency (%) of 95% for MB and 81% for RR198 were achieved with an initial dye concentration of 100 mg L–1, a sonocatalyst dosage 0.25 g L–1 (MB) and 0.1 g L–1 (RR198), an initial pH of 6.55, ultrasonic power of 90 W and ultrasonic frequency of 53 kHz. The thermodynamic parameters showed that the process was feasible and exothermic. In addition, the usage of non-modified TiO2 particles was found to be a feasible choice and give satisfactory results for the removal of aniline (cationic) and azo (anionic) dyes without the requirement of highly expensive modified methods.
