| Abstract: | A photocatalytic reactor was studied on a bench scale using solar light as the source of radiation to degrade soluble dye 4BS (red). The photocatalyst was titania immobilized on glass with the presence of ferric ions. The results showed that 4BS (red) was remarkably photolized under the experimental conditions. An initial 4BS (red) concentration of 25 rng/L was decreased to 3. 8 mg/L in about 30 minutes of irradiation. The influence of parameters,such as concentration of ferric ions,initial pH of 4BS (red),slope of the plate and flow,was tested. |
