In this study zinc ferrite nanoparticles were produced using chemical co-precipitation method from metal chloride precursors. Nanoparticle decorated chitosan coated alginate beads were manufactured for the removal of Pb (II) from waste water. X-ray diffraction (XRD) method was carried for the characterization of the prepared material. Adsorption isotherm study was carried out. The experimental data was correlated with the Langmuir and Freundlich isotherm models. The correlation coefficient (R2) calculated from the Langmuir isotherm for nanoparticle loaded beads was 0.996 and for alginate- chitosan beads was 0.991.The correlation coefficient for nanoparticle loaded beads and alginate- chitosan beads from Freundlich isotherm were 0.976 and 0.948 respectively. The values of the correlation coefficient indicate that Pb (II) adsorption onto nanoparticle loaded beads and alginate-chitosan beads is described very well by the Langmuir isotherm model, compared to the Freundlich isotherm model.
