Immobilized Tio2/Chitosan Layered System Incorporating Reactive Red 4 Dye For The Photocatalytic Degradation Of Phenol

An immobilized TiO2/chitosan layered system incorporating Reactive Red 4 (RR4) dye has been successfully fabricated, optimized and applied for the removal of phenol under a 45 W compact fluorescent lamp. The immobilized photocatalyst was prepared by adsorbing RR4 dye on chitosan (CS) sub-layer suppo...
