STUDY OF METHYL ORANGE PHOTODEGRADATION USING TiO2-MONTMORILLONITE COMPOSITE

Composite TiO2-montmorillonite (Ti-MMT) has been synthesized with the aim to improve the ability of TiO2 photocatalysts degrade methyl orange. Synthesis of composite made by mixing TiO2 and montmorillonite in ethanol solution, then heated using the furnace at a temperature of 450 °C for 5 hours. TiO2-MMT composites were characterized by FT-IR, XRD and SAA. Test photodegradation activity of TiO2-MMT composites made to dye Methyl Orange 8 mg / L with UV light irradiation time variation and mass-MMT composite TiO2. Photodegradation with UV rays performed in reactor 365 nm UV black light 10 watt 220 volt Gold Star. Photodegradation results demonstrate the ability of the composite activity of TiO2-MMT optimally occur at the time of UV irradiation for 330 minutes with methyl orange degraded as much as 81.4% and photodegradation reaction without UV rays generated methyl orange degraded as much as 33.25%. The optimum mass of Ti-MMT composites were used to degrade methyl orange is equal to 200 mg; Methyl Orange degraded by as much as 89.3% to photodegradation using UV light and 87.3% for photodegradation not use UV rays
