Optimasi Proses Degradasi Metil Violet pada Reaktor Fotokatalitik Film TiO2-PEG
Abstract: Methyl violet is one
of triphenylmethane dyes which has been used extensively in various industrial
application. Significant proportion of these dye enters the environment as
wastewater. Photocatalytic degradation by using TiO2 under UV light irradiation
has been shown to be potentially advantageous in the treatment of wastewater.
This research was aimed to determine the optimum thin layers of catalyst and
irradiation period of photocatalytic reactor. Modification by adding PEG was
done to enhance TiO2 activity. A decrease in methyl violet concentration was
analysed by using UV-Vis Spectrophotometer. GC-MS was used to ensure that there
were a degradation indeed. Experimental results showed the optimum thin layers
was reached in 8 times and irradiation
period was 5 hours. At this optimum condition, degradation percentage obtained
was 79,03% with the initial concentration used was 10 mg/L and the flow rate
was 110 mL/s. Identification by using GC-MS showed many peaks which proved
there were degradation processes.
