Photocatalysts based on titanium dioxide were used for purification of organic pollutants in water. The photo-catalytic decomposition of Reactive Black 5, a textile azo dye, has been investigated in aqueous heterogeneous solution containing semiconductor oxides as photocatalyst. Two types of photocatalysts were used in the reaction: Tytanpol All produced on Polish market by Police company and the most popular titanium dioxide-P25 produced by Degussa Company. The effect of operational parameters, i. e. photocatalyst content, dye concentration, pH of solution on the photocatalytic decomposition of Reactive Black 5 in water has been examined. The photocatalytic decomposition of RB5 was about 30% lower for All than P25 in all cases.
