Treatment of Industrial Dye Effluent by Photo-Catalytic Process Using Modified Egyptian Bentonite

Dyes are known to be harmful organic compounds for the environment since only a small amount of dyes can hazardous. So, treatment industrial dye effluent using commercial and effective catalyst is study's main objective. The adsorptive photocatalytic activity Egyptian bentonite was improved by acid treatment, followed incorporation cerium dioxide on surface via simple precipitation method then thermal calcination. natural modified (B-CeO2) samples were characterized XRD TEM-EDX techniques. removal% studied changing initiator, dosage, temperature, solution pH in dark visible light. maximum removal (91%) obtained acidic (6.34, normal effluent) 2 g/L 5 mM/L ammonium persulfate, 200 W lamb at 40 oC with constant stirring. results indicated that has high due synergism between effect light, CeO2, exfoliated/delaminated bentonite.
