The biosorption of Cd(II) ions from aqueous solutions by dried activated sludge was investigated as a function
of initial pH, initial cadmium ion concentration, adsorbent mass, adsorbent particle size and temperature. Biosorption
experiments were performed using activated sludge of the systems of wastewater refining of milk factory.The results
showed that The maximum adsorption capacity of the sludge increased as the temperature increased. Increasing the
adsorbent particle sizes and the initial cadmium ion concentration decreased the removal efficiency, but Increasing the
initial pH and the adsorbent mass increased the removal efficiency. The equilibrium data fitted very well to both
Langmuir and Freundlich adsorption models.
