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.

Removal of heavy metals from industrial wastewater is of primary importance. The use of natural materials for heavy metals removal is becoming a concern in all countries. The application of low-cost natural adsorbents including carbonaceous materials, agricultural products and waste by-products has been investigated in many previous studies [1-3] which have been recognized as potential alternative to the conventional technologies such as precipitation, ion exchange, solvent extraction and liquid membrane for removal of heavy metals from industrial wastewater because these processes have technical and /or economic constraints. The important toxic metals i.e., Cd, Zn Cr, Cu and Pb finds its way to water bodies through from such industries as metal plating industries of cadmium, nickel and lead battery industries, pigments, stabilizers and alloys [4]. Lead is used as prime material for lead storage batteries and it is present in aqueous solution as waste water generated from battery manufacturing industries. Lead poisoning can cause convulsions, coma and even death. Intermediate lead poisoning may results in gastrointestinal, haematological and cardiovascular disorders while low level toxicity is associated with decrease intelligence impaired neurobehavioral development stunted growth and decreased hearing capacity. The conventional methods for heavy metal removal from aqueous solution of wastewater include reduction, precipitation, ion exchange, electrochemical reduction evaporation reverse osmosis and adsorption. Most of these methods involve high capital cost with recurring expenses, which are not suitable for small scale industries. Studies on effluents of aqueous solution bearing heavy metals have revealed that the adsorption to be highly effective, cheap and easy method among the physico-chemical treatment processes owing to high cost and difficult procurement of activated carbon efforts are being directed towards finding efficient and low cost materials.
