Kinetic evaluation of photocatalytic decoloration of Synozol Red K3BS dye using TiO Volumen 8, número2-anatase and direct solar radiation

Abstract

The intense solar radiationBiotecnologíaof the /cityBiotechnologyof Arequipa has been used as an activation factor for TiO2 anatase to evaluate the decoloration kinetics of the Synozol Red K3BS textile dye. For this purpose, a factorial design (23) was developed to optimize reaction time values, pH245andModeladoTiO2 dosesde laforbiodegradación200 mL of solution.en biorreactoresThe optimaldefactorslodos forde thehidrocarburosstudy were:totalesa 60 mindel duration,petróleo a pH of 3 and 0.1 g of photocatalyst. The first-order kinetic model adequately explained the decoloration of a solution at a concentration intemperizados en suelos y sedimentos of 40 mg/L, showing an excellent reaction rate constant (k=0,0333 min−1) and a decoloration percentage of 86.15%.
