【 摘 要 】

The adsorption of Rhodamin B on Iraqi bentonite at the concentration range from 50 to 250 ?g mL^-1 was studied, Nano compounds; ZnO, TiO₂, Al₂O₃ m and SDS in different amounts 0.01-0.1 g 10^-1 g of Bentonite were used to modified the adsorption capacity of bentonite to remove the Rhodamin B from aqueous solutions. The study indicated that using 0.05 g and 0.1 of Sodium Dodecyl Sulfate (SDS) lead to increase the percentage removal (%R) from 79.3% for pure bentonite to 99.3%. While using 0.05 g TiO₂ lead to increase the %R to 98.9%, 0.05 of ZnO to 98.6%. The other amount additives and Al₂O₃ using was not success to increase the %R for the Rhodamin B on bentonite surface. SEM measurement was achieved to discover the Nanoparticl exists in the bentonite surfaces.
