Abstract
Degradation of rhodamine-B dye using sonolysis and photolysis methods by addine anause-TiO2 had been done. Sonolysis method was performed using an ultrasound with frequency of 47 kHz. The optimum condition for degradation of 2mg/L rhodamine B using sonolysis with addition of 0.1000 g anatase-TiO2 were found at pH= 5, temperature 40 ± 1o C, with the percentage of degradation of 46.41 %, within 120 minutes. Photolysis method was performed using an irradiation of UV light with λ = 365 nm. Desradation of 2 mg/L rhodamine-B using photolysis with addition of 0,1000 g anatase-TiO2 was optimum at pH = 5 and percentase of degradation 93.49 % within 120 minutesphotolysis. Keywords: degradation, sonolysis, photolysis, anatase-TiO2, rhodamine-B. dye.
