Abstract


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.
