Photocatalysis of Orange – 84 Reactive dye using a sunlight collector
Journal Title: Revista Lasallista de Investigación - Year 2007, Vol 4, Issue 2
Abstract
Introduction. Reactive Orange 84 is a dye used in the textile industry, specifically in cotton clothing, which generates a hightly colored residual water, because only 65% of this water is impregnated and the 35% remaining hydrolyses in water, generating a highly colored waste water Objective: To study photocatalysis of Reactive Orange 84 by the use of a sunlight collector and titanium oxide as a catalyst. Materials and methods: A sunlight collector made up by three modules (each one made up by eight glass Schott-Duran pipes) was used. Each glass pipe is 48 cm of external diameter and 150 cm long and also contains an aluminum sheet, which allows the reflection of sunlight. The whole device had a re-circulation bomb and a tank. The sunlight collector had an inclination of 6 degrees in comparison with the floor and was facing north because it must be located according to the geographic position of the place. Only one condition was modificated for each experiment with the objective of studying its influence in the dye’s degradation. In this research work we show different combinations of hydrogen peroxide, titanium dioxide and air, used in the photo catalysis of the 84 Orange reactive and waste water samples from textile industry. Results: The optimal concentrations found for 84 orange reactive in a 340 mg/lL concentration are: 40 mg/L of titanium dioxide and 2 mL/L of hydrogen peroxide with no air injection. Conclusion: With an appropriate quantity of titanium dioxide and a well calculated concentration of hydrogen peroxide, very good concentration percentages of the 84 orange reactive and colored waste waters are obtained, besides of high mineralization percentages
