Abstract

The purpose of recent work is to evaluate the effects of TiO2 in degrading organic wastewater. Technical TiO2 of anatase crystalline phase was used. TiO2 photocatalyst showed a powerful result in destroying organic effluent. Dip coating was conducted to immobilize the TiO2 particles onto the plastic buffer followed by putting the additional polymer (alteco glue). As a result, 100 mL of 25 mg L-1 methylene blue (MB) used in the photocatalyst test was successfully degraded after 12 hours of irradiation. Variation of TiO2 concentration and additional polymer was carried out to study the performance of the catalyst.
