REMOVAL OF LEAD IONS BY NIFE 2O4 NANOPARTICLES

Nickel ferrite nanoparticles have been prepared by polymeric precursor method. The nanoparticles appli cation in the removal of lead ion was investigated. The results showed that the a dsorptive properties were dependent on pH, duration and temperature. Highest percentage (99%) lead adsorption was observed under basic condition at room temperature during 1 h sti rring. Analysis of lead adsorbed nickel ferrite by powder XRD, FTIR and XPS techniques revealed the adsorption took place base d on hydroxide mechanism. The lead salt formed on the surface of the ferrite powder was identified to be lead carbonate and lead hydroxy carbonate at pH 7 and 9 respectively.
