This book describes the removal of Malachite Green (MG) dye by Zeolite and Zeolte-Lanthanum Oxide Nano Composites were investigated. Lanthanum Oxide nano particles were prepared by Precipitation Method and Zeolte-Lanthanum Oxide Nano Composites were prepared by impregnation method. Zeolite and synthesized Zeolite-Lanthanum Oxide nanoparticles composites were characterized by FTIR spectroscopy, X-ray diffraction (XRD), Field emission gun scanning electron...
