Abstract

Degradation of Sudan I dye had been done with sonolysis and photolysis by adding anatase-TiO2. Sonolysis method were performed using an ultrasound with frequency of 45 kHz. Photolysis method were performed using an irradiation of UV light with λ = 359 nm. Degradation of 4 mg/L Sudan I with addition of 0.1000 g anatase-TiO2 at pH = 7.0, temperature 25 ± 1°C, percentage of degradation 64.04% within 180 minutes sonolysis. Degradation of 4 mg/L Sudan I using photolysis with addition of 0.1000 g anatase-TiO2 at pH = 7.0 and percentage of degradation 100% within 180 minutes photolysis. Degradation of 4 mg/L Sudan I using sonolysis and photolysis simultaneously with addition of 0.1000 g anatase-TiO2 at pH = 7.0 and percentage of degradation 94.04% within 180 minutes treatment. Keywords : degradation, sonolysis, photolysis, Sudan I, anatase-TiO2.
