Abstract

Degradation of methyl violet dye had been done by photolysis and sonolysis with adding TiO2/SiO2 catalyst. This study aims to determine the optimum time for degradation and optimum dopan silica (SiO2). Photolysis method were performed using an irradiation of UV light l= 254 nm and sonolysis  using an ultrasound with frequency 45 kHz. Result methyl violet degradation products obtained under optimum conditions identified by GC-MS. The optimum time for degradation of methyl violet photolysis is 270 minutes, the addition of silica optimum dopan occurs on addition of  25% SiO2, with percentage of degradation (%D)  is  96.52%.  The optimum  time in the degradation of methyl violet  in sonolysis photolysis is 270 minutes and the addition of silica optimum dopan occurs on addition of  25% SiO2, with percentage of degradation (% D)  is  76.19%. Identification of the GC-MS results obtained showed many peaks that have occurred in the degradation of methyl violet molecules.
