The increased release of poisonous heavy metals such as Lead (Pb) has severely caused environment as well as public health problems. Thus, the removal of lead by economical and conventional ways is of great importance. This was done by using Sulphonated powder of inner layer of Cassava and the uptake percentage was determined at various pH, time and adsorbent by using AAS. It was found that the amount of lead adsorbed increases with the decrease in the pH and was found to be maximum at pH of 2.0 where there was around 40% removal of the lead. With increase in time, the adsorption increases following the Langmuir model of adsorption isotherm. Also, the concentration of the adsorbent was found to be directly proportional to the amount of lead adsorbed as it increased from 40% at 1g to 51% at 2g keeping the pH of the solution constant.
