Removal of Lead from Aqueous Solution using Unglazed Porcelain

MA Hussain*, S Kausar and Rajeev Singh

A detailed study was conducted to remove lead from aqueous solution by using unglazed porcelain. The optimum dose of unglazed porcelain adsorbent can remove 96% Pb, from aqueous solution containing 10 mg/l of initial concentration. The effect of pH range on adsorbent sample was selected between pH 2 to pH 12 and optimum value of this parameter was pH 6. The granular porcelain was used adsorbent in suspension form was filtered and filtrate was analysed for the Lead (Pb) concentration in aqueous solution with help of atomic absorption spectrophotometer using air acetylene gas. Column operations were also carried out on the actual waste for evaluation of break through capacity and lead removal from actual waste. The data collected during experiments have shown good results for different parameters, at optimum concentration (10 mg/l) for optimum pH 6, at the optimum does (400 mg/l). The percentage adsorption was maximum (99%) under these conditions. The data also follows the Langmuir and BET isotherms and their equations.
