ABSTRACT
Carbonized coconut Shell was used for the adsorption of Cu2+ from aqueous solutions using Batch adsorption method. The result for physico-chemical characterization give the ash content to be 3%, moisture content as 11%, 45% for attrition, the tap density was 0.3 g/mL, pH as 6.24 while the iodine number was found to be 46.90%. The equilibrium adsorption was studied and the result fitted into the Temkin model. From the results obtained, the adsorbent proved to be an effective adsorbent for the removal of Cu2+ from aqueous solutions. Atomic absorption spectrophotometer was used to monitor the adsorption of Cu2+, the optimum values obtained were 50.2 % at 20 mg/L for concentration, 99.60 % at a pH of 99.6%, 59.9 % at a contact time of 40 minutes and 50.9 at an adsorbent dose of 5 g, from the results, coconut shell is a good adsorbent for the removal of Cu2+ from aqueous solution.
