Abstract

The isotherms, kinetics and thermodynamics of bath sorption of copper (Cu) on activated carbon from African bush mango seed shell (ABMSS) have been investigated. The effects of initial concentration, dosage contact time, and pH were examined. The results showed that adsorption capacities of the activated carbons decreased with increase in initial concentration of copper. The process sorption followed a pseudo second order kinetics. It could be best fitted by Langmuir isotherms with R2 value of O.99. The thermodynamic parameters such as ΔH, ΔS and ΔG were computed from experimental data. These values show that adsorption is endothermic and non-spontaneous. Moreover the relative weak values of ΔH (207.85 kcal/mol) confirm a physical adsorption. The maximum adsorption of copper onto ABMSS activated carbon were obtained at contact time of 70 minutes, pH of 8, adsorbent dosage of 10g/l, with Copper initial concentration of 50mg/l .
