The present study involves the photocatalytic decolorization of Carmine XIE (reactive) dye by employing newly synthesizes heterogeneous photocatalytic under laboratory condition. An attempt has been made to study the effect of process parameters viz., amount of catalyst, pH, and irradiation time of photocatalytic degradation of Carmine XIE dye Carmine XIE (reactive). The experiment was carried out by irradiating the aqueous solutions of Carmine XIE dye containing photocatalysts inside the batch reactor having UV light. The rate of decolorization was estimated from residual concentration by spectrophotometrically. Similar experiments were carried out by varying pH (2–14), the amount of catalyst (0.05–1 gm) time variation (2-30) minutes). The experimental results show that, the maximum decolorization of Carmine XIE (more than 90%) occurred at pH 7-11 using newly synthesized photocatalyts. The performance of catalyst was excellent throughout the experiment and excellent results are obtained.
