| Abstract | ||
| Photocatalytic degradation of Hydroquinone (HQ) dissolved in aqueous TiO2dispersions under UV and near visible light has been investigated . The first experiments were used to determine the optimum value of TiO2,it was found that using 10 mg of TiO2 in 25 cm3of aqueous solution produced the highest degradation of rate constant . The effects of sodium dodecyl sulphate (SDS) and Rodamine 6G(Rod 6G) dye on the photocatalytic degradation of hydroquinone (HQ) have been studies .The results of degradation was observed that the rate of photodegradation was decrease with increasing of SDS concentration , while the results indicate that the rate of photodegradation was increased whenRod 6G dye was used. According the experimental results, the general reaction mechanism for this compound was suggested. | ||
