Abstract

Degradation tests were carried out to determine the luminous intensity influence on textile industry effluent photodegradation. TiO₂, Nb₂O₅, Nb₂O₅-TiO₂ and Nb₂O₅/TiO₂ were used as photocatalysts. FTIR (Fourrier Transform Infrared) and TPR (Temperature Program Reduction) results showed interaction between different forms of the oxides in the Nb₂O₅-TiO₂ and Nb₂O₅/TiO₂ catalysts and the forming of a new phase in Nb₂O₅-TiO₂. The reaction rate was significantly influenced by the luminous intensity. Luminous intensity decrease caused decolourisation increase and COD reduction decrease, suggesting that the concentration of the hydroxyl groups, which are responsible for the chromophores groups degradation, is proportional to the luminous intensity
