“…pair of P25. Qamar et al (2005) also tested the photocatalytic activity of three different commercially available TiO 2 powders (namely P25, UV100 and PC500) on the degradation kinetics of chromotrope 2B and amido black 10B. They observed that the degradation of both dyes proceeds much more rapidly in the presence of Degussa P25 as compared with other TiO 2 samples.…”

“…The degradation rate for the decomposition of the dye was found to increase with an increase in catalyst concentration, (Saquib and Muneer 2003). Qamar et al (2005) found that the degradation rate for the decomposition of chromotrope 2B and amido black 10B increase with the increase in catalyst concentration. The investigation was done in different concentrations of Degussa P25 varying from 0.5 to 5 g/l.…”

Traditional chemical, physical and biological processes for treating wastewater containing textile dye have such disadvantages as high cost, high energy requirement and generation of secondary pollution during treatment process. The advanced oxidation processes technology has been attracting growing attention for the decomposition of organic dyes. Such processes are based on the light-enhanced generation of highly reactive hydroxyl radicals, which oxidize the organic matter in solution and convert it completely into water, CO 2 and inorganic compounds. In this presentation, the photocatalytic degradation of dyes in aqueous solution using TiO 2 as photocatalyst under solar and UV irradiation has been reviewed. It is observed that the degradation of dyes depends on several parameters such as pH, catalyst concentration, substrate concentration and the presence of oxidants. Reaction temperature and the intensity of light also affect the degradation of dyes. Particle size, BETsurface area and different mineral forms of TiO 2 also have influence on the degradation rate.

Ultrasonic cavitation induced degradation of Congo red in aqueous solution was investigated for a variety of operating conditions. It is found that the degradation of Congo red in aqueous solution follows pseudo-first-order reaction kinetics and the degradation rate is dependent on the initial concentration of Congo red, the temperature and pH of the aqueous medium. The effects of Fe 2+ and Fenton reagent addition on the sonochemical degradation of Congo red were also investigated. The results obtained here indicate that the degradation rate of Congo red in aqueous solution was substantially accelerated by Fe 2+ , NaCl or Fenton reagent addition.

“…1). This rapid reduction could be partially explained by means of photobleaching of the extracts due to some possible oxidative reaction [26] . The values of the fitted parameters of Eq.1; ratio a and the rate b are higher values under the influence of light as compared to temperature ( Table 2).…”

Addition of inulin and hydrogen peroxide to new photosensitizers extracted from the flowers and aerial parts of the chicory (Cichorium Pumilum Jacq) have been investigated. Some of the isolated photosensitizers remain unidentified compounds. Chicory extracts are found to be dependent on light and temperature. Higher photohemolysis rate was noticed under the influence of light as compared to temperature. The effect of H 2 O 2 on phototoxicity reported in this study showed a rapid reduction in the fractional hemolysis percentage at higher temperature. Compared to erythrocytes with higher concentrations and under the influence of solar irradiance 505.29±24.96w/m 2 , erythrocytes with lower concentrations of inulin and H 2 O 2 were ruptured faster. Samples with 0.95mg/ml of herb extract and different concentrations of inulin (1mg/ml -2mg/ml) shows no temperature effects at 40 C in the absent of sunlight.
