Abstract

Degradation of naphtol blce black dye had bent done by seaolysis and phelolysi with adding anatase TiO2. Sonolysis method were performed using ar. ultrasound with frequency 45 kHz_ and photolysis using an irridia:ion of UV lidrt %= 359 run. The optimum condition for dcgadation of (j m,-j1. naphtol blue black by sonolysis with addition of 0.1000 g antase-TiO2 were fourd at pH = 3.0 and temperature 30 ± IoC. Percentase of degradation at pH and temperature, optimum was 65,20% within 120 minutes treatment. Degradation of 6 rng/L naphtol blue black by photolysis with addition of 0.1000 g anaiasc-TiO: was optimum at pH-3.0 and percentage of degradation was 6S.7-2'.b within 12U minutes irradiation without stirring. The combine of ionoiysis and photnly.Sis met od simultaneously for degradation of naphtol blu-. black dye by adding anar are-TiO2 achieved 92.51% degradation after 60 minutes treatment.
