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 45kHz .Phoptolysis method were performed using an irradiation of UV light with λ=359 nm. Degradation 64,04% within 180 minutes sonolysis. Degradation of 4 mg/L Sudan I using photolysis with addition of 0,1000 g anatase-TiO 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-TiP2 at pH = 7,0 and percentage of degradation 94,04% within 180 minutes treatment.
