Abstract

The decolorization of Turquoise Blue G, a reactive copper-phthalocyanine dye, by titanium dioxide photocatalysis was investigated. The highest average color reduction of titanium dioxide photocatalysis was investigated.The highest average color reduction of 32.75% and 16.555 were achieved under UV light and white light, respectively. By the two-tailed t-test (tcalc=3.0827,α =0.05, df=126), it was concluded that there is a significant difference on the responses upon irradiation with the two different light sources. T the analyses of the 2⁶ full factorial design of experiment brought out that initial dye concentration is the most important factor for the photocatalytic oxidation while pH is the most significant for the photosensitized oxidation. Moreover, all of the investigated parameters have been significant on the UV-irradiated runs while only the initial dye concentration, pH and temperature have considerable effects on the treatments with visible light. With regards to the two-factor interactions, only the interaction between concentration and temperature have been insignificant to the photocatalytic oxidation while only the interactions of temperature with initial dye concentration, pH and catalyst loading have exhibited significant effects to the sensitized dye solutions. By incorporating the significant terms evaluated, regression models were formulated. Good fits were observed as adjusted regression coefficients of 0.9859 and 0.9559 were computed for the UV light and visible light treatments, respectively.
