摘要：
This paper focused on adsorption process for metals removal from landfill leachate using oil palm shell as adsorbent. Raw shells were grinded to sizes of about 2 mm, followed by heating in at 420°C for a period of 4 hours. Batch test indicated a removal of more than 60%Cd and Pb from leachate samples. The removal process agrees with the Freundlich isotherm model. Column test for continuous flow performance shows efficiency ranging 30% and 80% for Cd and Pb. The efficiency depended on Empty Bed Contact Time, which was verified in the range of 20-100 min. Copyright © 2009, Inderscience Publishers.
