摘要: In this work, coffee husk based activated carbon (CHAC) was prepared by physicochemical activation for the removal of Remazol Brilliant Orange 3R (RBO3R) dye from aqueous solution. The effects initial concentration, contact time, solution temperature and pH on RBO3R adsorption were investigated. Result showed that favorable at acidic pH. uptake found to increase with in time temperature. Langmuir isotherm model fitted well equilibrium data monolayer saturation capacity 66.76 mg/g 303 K. kinetic follow pseudo-second-order model. Boyd plot indicated CHAC controlled film diffusion. process be endothermic reaction mechanism follows a physisorption process.
