Abstract

This studyinvestigates the efficacy of photocatalytic degradation process using TiO₂-UV configuration for treatment of waste water containing textile dye Acid Yellow 36 (AY36).Acid Yellow 36 dye was degraded using catalyst TiO₂ in analkaline medium of pH8.0.A dose of 0.25g of TiO₂ was used for 88.4% degradation of initial concentration of 20mg/l AY36 dye in 28 hrs. The effect of parameters such as pH, initial dye concentration, amount of TiO₂used, and exposure to UV light/irradiation on degradation of AY36 was investigated.Further it was observed that suspended TiO₂ in dye solution shows more effective results towards dye degradation, than embedded TiO₂ in the form of alginate beads. The study concluded that photocatalytic degradation is a potential tool for degradation of azo dyes.
