Removal of cadmium metal ion (Cd2+) from its aqueous solution by aluminium oxide (Al2O3): A kinetic and equilibrium study

In this work, the effects of various experimental parameters on kinetics and equilibrium adsorption of Cd2+ metal ion from its aqueous solution on aluminium oxide (Al2O3) have been investigated using batch adsorption experiments. It has been found that the amount of adsorption of metal ion increa...
