Sorption mechanism of Co2+ ions by AlPO4.
Sorption studies were conducted for Co2+ ions on AlPO4 at different concentrations and temperatures. Sorption of Co2+ was found to increase with increase in concentration and temperature. To determine the mechanism of the sorption process, dissolution of AlPO4 in the presence of Co2+ ions and desorption studies were performed which indicated the mechanism of sorption to be the ion exchange followed by precipitation. FTIR studies were also employed to confirm the proposed mechanism.
