Abstract

Lead is a heavy metal which has many applications in different industries. Due to toxicity of lead, discharging industrial effluents which contain these ions will bring irreversible risks to the environment and living ecosystems. The objective of this study is to analyse the use of Eucalyptus Sawdust as a cheap adsorbent for Lead Removal from effluent. The experiments were conducted in batch system and the effect of pH, the amount of adsorbent, contact time and the initial concentration of lead were examined. Noticing the results, the maximum efficiency of lead Adsorption is 96. 25% which was obtained in pH of 7 and contact time of 30 minutes and 10 g/L of adsorbent. By increasing the initial concentration of lead, the adsorbed metal and removal percentage also increased. Achieved data from this study indicated a good compatibility with Langmuir Adsorption isotherm. Kinetic analysis indicated that lead Adsorption matches with the second-order kinetic Adsorption model (R2=0. 998). Noticing the high efficiency of Lead Removal by Eucalyptus Sawdust, this method could be used as an effective and cheap adsorbent for Lead Removal.
