主　　题：physical chemistry loaded photocatalyst TiO_2 acridine dye fluidifying sedimentation container 

摘      要：A new photocatalyst, TiO_2 powder immobilized on polystyrene (PS) thin films,was prepared using a novel method and its photocatalytic activity on the photodegradation ofacridine dye in aqueous solution was tested. By this method, the crystal form and grain size of theimmobilized TiO_2 were well maintained. Compared with TiO_2 powder, the photocatalytic activity ofTiO_2/PS thin films was not significantly reduced. The catalyst is stable and can be reused severaltimes without the loss of activity, which makes wastewater treatment using this photocatalyticdegradation technique of this way possible in the practical application.
