摘要: A B S T R C Organic contaminants from industrial and/or domestic effluents may be harmful to humans directly or indirectly by degrading the quality of environment. Consequently these must reduced levels that are not and environment before disposal. Among available chemical methods heterogeneous photocatalytic oxidation has been found particularly effective in removal large number persistent organics water. Degradation was achieved exposing synthetic UV light a reactor dark compartment presence catalyst. The degradation RO16 conducted at pH 5.5, 24 hr, 294 K lamp power 200 W. prepared ml dye solution with concentrations 20, 40 60 mg/L took place TiO2 (0.5-4.0) g/L. While photolysis (in absence TiO2) have no effect on RO16, photocatalysis catalyst) degraded 0.4 mg/L.
