Abstract:The effects of Cu (Ⅱ) or Zn (Ⅱ) on the photo-catalytic degradation of some organic chemicals in water, such as acetone, phenol, dyes, and tea saponin were studied. Dyes in wastewater from a textile factory can be effectively degraded by photo-catalysis with TiO2 and ultraviolet light or sunshine, but the reaction rate could be slowed down if copper or zinc salt exists in the solution.
Key words: photo-catalytic degradation; titanium dioxide; dye wastewater; acetone; phenol; tea saponin
