Abstract
In this research, activated carbon (A.C) and non-activated carbon (N.A.C) have been produced from heavy crude oil wastes by distillation operations, carbonization and activation. Anhydrous zinc chloride (ZnCl2) (10% W/V) have been used for activation process with temperature of (500) ºC. Adsorption processes of Nitrobenzene on the surface of (A.C) and (N.A.C) have been studied at (pH = 7) with various periods for contact (10-120) minutes and with temperatures of (283, 293, 303, 313) K, using solutions of (50, 100, 150, 200) mg L versus grain size of carbon (Mesh 70). The results showed that the percentage of adsorption increases with increasing of temperature and contact time. The highest percentage of adsorption of Nitrobenzene reached to (98.40) %, using (A.C) and solutions of (100 mg L) concentration at contact time of (120 minutes) and temperature of (313 K), whereas a higher percentage of adsorption of Nitrobenzene reached to (97.05) %, using (N.A.C) at the same previous conditions.Equations of Frendlich, Langmuir and Temkin have been applied on the adsorption processes. The results showed that all of the equations fit with adsorption processes according to correlation factor values (R2). The thermodynamic functions have been calculated. Values of (ΔGº) showed that the adsorption processes were spontaneous. Values of (ΔHº) showed that the adsorption processes were physisorption and endothermic.
