Kinetic and Thermodynamic Studies of Cd2+, Cu2+ and Pb2+ Removal by Decanter Cake from Palm Oil Mill

Palm oil mills generate about 4-5 tons of decanter cake for every 100 tons of palm fresh fruit bunch processed. Due to the high organic content, the decanter cake could be converted into adsorbent for the removal of metal ions in waste water. The decanter cake was first dried at 105oC and then carbo...
