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

In this study, nanocomposites of Ce-TZP/Al₂O₃ 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°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.
