The application of low cost, available and eco-friendly adsorbents has been investigated as an ideal alternative to the current expensive methods of removing dyes from wastewater. The use of activated carbon prepared from Irvingia Gabonensis for the removal of methylene blue from simulated effluent water has been studied. The contact time results showed that equilibriumwas attained at 100minutes and that the smaller-sized adsorbents were more efficient in removing colour fromeffluent water than the largesized adsorbents. The equilibrium sorption fitted into the Langmuir and Freundlich adsorption isotherms. Thus activated carbon from Irvingia Gabonensis can be an attractive option for the removal of dyes from diluted industrial effluents.
