Abstract

In this paper photocatalysis processes on titanium dioxide suspension in aqueous solution illuminated with UV light are described for decolorization and Chemical Oxygen Demand (COD) removal of landfill leachate. Several operational parameters to achieve optimum efficiency are presented. The properties of the decolorization and COD removal were enhanced and studied by spectrophotometer methods. The results indicate that the process can be used as a pretreatment to the conventional processes.
