Removal of lead (II) from aqueous solutions by Eucalyptus leaf abstract
In this study, Eucalyptus was used as an adsorbent for the removal of Lead from aqueous solutions. The effect of operating variables namely initial pH, sorbent dose, initial metal concentration, contact time, strength ionic and temperature on the Lead removal percentage and uptake capacity has been studied. The optimal pH was found as 3.0 and the sorbent dosage 0.5 g/L. The experiments showed that the adsorption process was quick and the equilibrium attained within 30 min. Evaluation using Langmuir gave sorption capacity 7.54 mg g-.1 Lead uptake by new adsorbent was best described by pseudo-second order model. Using the equilibrium concentration constants obtained at different temperatures, various thermodynamic parameters have been calculated. The results indicated that Lead adsorption was feasible, spontaneous, and endothermic
