摘要：
Activated carbon-immobilized-cationic surfactant (AC-CS) was designed to enhance the decolorization behavior of reactive black 5 (RB5), as an anionic dye, from aqueous and industrial wastewater samples in presence of various controlling experimental conditions. Experimental data indicated that the dye adsorption capacity by (AC-CS) was higher in strongly acidic and basic solutions. An anion exchange and ion-ion interaction mechanisms were proposed in the acidic solution, while only anion exchange mechanism was suggested in the-basic aqueous solution. The adsorption behavior and thermodynamic parameters were also evaluated. Treatments of textile industrial wastewater and real water samples were successfully established (9523-100.00%).
