Adsorption is as an alternative technology to remove colour from wastewater. In this study, activated carbon, prepared from low cost palm oil fibre has been utilised as theadsorbent for the removal of basic dyes from aqueous solution. A basic dye, Methylene Blue has been used as the adsorbate. Experiments were conducted by varying several parameters namely pH, adsorbent dose, initial concentration of dye and contact time. Colour was effectively been removed at all selected pH, and the increase in activated carbon dose showed an increase in the removal’s percentage. The percentage of colourremoval decreased with increasing of initial dye concentration. The adsorption equilibrium for colour was reached after 90 minutes of contact time. The adsorption followed bothLangmuir and Freundlich isotherms. Results obtained indicate that palm oil fibre could be employed as a low cost alternative to commercial activated carbon in wastewatertreatment for dye removal.
