The precursors were first carbonized at 600 °C in N 2 atmosphere and then activated with steam at 850 °C. Carbons obtained were then subjected to physical and structural analysis. The results indicated that the composite activated carbons obtained had micropores which were narrower and as such showed higher adsorption capacities of iodine and methylene blue as compared to activated carbons from oil palm shells and synthetic polymer prepared under the same conditions. All the samples had large surface areas (800 to 1500 m 2 /g) and pore sizes in the range of 0.4 – 0.9 nm, characteristic of microporous solids. Infrared (IR) investigations showed enough hydroxyl and carboxylic functional groups on the surfaces. Scanning Electron Microscopy (SEM) showed that the composites activated carbons pore walls were thinner and smoother compared to the activated carbon from lignocellulosic material. Finally Raman spectra exhibited a D-band at 1350 cm -1 and G-band at 1600 cm -1 showing further disorder into graphene layers. However, the main characteristic of the obtained activated carbon was the
