DEGRADASI METHYL VIOLET SECARA FOTOLISIS DAN SONOLISIS DENGAN KATALIS TiO2/SiO2
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.
