Abstract

In this research work, lynde type Zeolite (LTA-Zeolite) nanoparticles (ZANPs) were synthesized using kaolin obtained from Darazo Bauchi State, the X-ray fluorescence (XRF) result shows SiO2,  Al2O3 percentage of 60.247 and 38.316 respectively and SiO2/Al3O2 ratio of 1.57 which is suitable for the synthesis of Zeolite-A. The produced nano adsorbent was characterized using X-ray fluorescence (XRF), X-ray powder diffraction (XRD), scanning electron microscopy (SEM), Fourier transform infrared spectroscopy (FT-IR), Ultraviolate-visible spectroscopy (UV-visible spectroscopy) and N2-Brunauer–Emmett–Teller(BET)surface analysis. The SEM micrographs revealed well-dispersed Zeolite-A nanoparticles (ZANPs) and the N2-BET showed a high surface area of 106.250m2/g, pore diameter of 2.1132 (nm) and a pore volume of 0.052 (cc/g)  for ZANPs. The array of removal of Heavy metal pollutants Pb, 96.0% Cr, 90%, ZANPs removing a higher percentage of Lead pollutants. Isothermal models indicated that the Freundlich model (R2)of 0.999 was most suitable for describing the adsorption process, which conformed to pseudo-second-order kinetics(R2) of 0.999Cr.
