Purification of water from heavy metal of lead by nanocomposite of Ce-TZP/Al2O3

In this study, nanocomposites of Ce-TZP/Al(2)O(3)with four different mole percent of alumina from 20% to 80% were prepared by aqueous combustion synthesis method and effects of alumina mole fraction on the adsorption of lead ions were investigated. Lead (Pb2+) ion adsorption process was performed at the temperature of 25 degrees C, contact time of 100 minutes for all the samples. The results showed that as the alumina content increases in the nanocomposite, the adsorption capacity of lead increases which was 63.72% for the nanocomposite containing 80% alumina. X-ray diffractometry and scanning electron microscopy were applied to characterize the powders and the samples after the adsorption reaction.
