In this study, Cd(II) ions adsorption from synthetic wastewater was investigated in batch mode using locally available maple sawdust. The equilibrium adsorption quantity was determined to be a function of the solution pH,initial concentration, contact time, and sawdust dose. The equilibrium adsorption results closely followed both the Langmuir and the Freundlich isotherms, but somehow it was well fitted to the Langmuir isotherms. According to the parameters of the Langmuir isotherm, the maximum Cd(II) ions adsorption capacity (q(e)) onto maple sawdust was found to be 7.429 mg/g that was very close to other adsorbents.
