Garlic peels have been used for the production of Carbon by treating with conc.H2SO4 for metal ions removal. Fourier Transform Infrared Spectroscopy and Boehm titration have been used for various physicochemical characterization of the outcome of activated carbon which proclaimed the presence of oxygen containing surface functional groups like phenolic, lactonic and carboxylic in the carbons. In a batch adsorption process the effect of pH and initial metal ion concentration was calculated. The optimum pH for lead adsorption is found to be equal to 6.The resultant activated carbon showed maximum adsorption capacity of Pb (II) was 210 mg g-1. The waste material which is used in this work is cost effective and easily available for the production of activated carbon. Hence the removal of Pb (II) from water using the carbons prepared from Garlic peels can act as possible low cost adsorbents for the removal of Pb (II) from water.
