Activated carbon prepared from Typha Angustata.L was used as adsorbent for the removal of Cd (II) ions from aqueous solutions. The effect of operating as a function of contact time, initial pH, initial adsorbent dosage and metal ion concentration and temperature also investigated, were the equilibrium adsorption data were fitted to Langmuir and freundlich adsorption isotherm models. The kinetic study indicated that the pseudo second order rate equation better described the adsorption process. The values of the separation factors are in the range of 0-1 which indicates favourable biosorption. The results indicated that the prepared activated carbon is an efficient, alternative low- cost adsorbent for the removed of cd (II) from aqueous solutions.
