Crude oil is a toxic environmental pollutant which needs to be removed from domestic water sources. In this work, Almond seed shell activated carbon (ASSAC) was explored for the treatment of crude oil polluted water. The almond seed shell was prepared and carbonized at 400 o for 240 min. From the analysis of the results, the adsorption of crude oil emulsion from Biseni crude oil polluted water onto ASSAC was better represented by Temkin isotherm. The kinetic study shows that the removal of crude oil emulsion from the sample onto ASSAC followed the pseudo second order adsorption model. The thermodynamic parameters for the removal of crude oil from the crude oil polluted water were an enthalpy of 3.27 kJ/mol, entropy of 12.1 J/mol.K and Gibbs free energy of 0.503 J/mol.K. These results shows that ASSAC, has the potential for the removal of crude oil emulsion from crude oil polluted water.
