ADSORPTION STUDIES AND FLUORIDE REMOVAL FROM AQUEOUS SOLUTIONS BY GRAPHENE OXIDE - ZINC OXIDE NANOCOMPOSITE

[摘要] Drinking water offers several essential elements for the human beings; however the existence of a few dissolved elements other than acceptable concentration can cause danger to health of humans. In general the suspended elements in water have fluoride, but fluoride at very low concentrations or at very high concentrations may cause undesirable health effects. Hence it needs to be placed at acceptable levels. In the present study, we report synthesis and characterization of graphene oxide - zinc oxide nanocomposite and their usage for fluoride removal is discussed. The graphene oxide - zinc oxide nanocomposite adsorbent offers a synergy toward fluoride removal from contaminated drinking water.Thus prepared graphene oxide - zinc oxide nanocomposite and the effects of contact time for the removal of fluoride were evaluated . The Langmuir and Freundlich isotherms were utilized to explain adsorption equilibrium for fluoride removal by graphene oxide - zinc oxide nanocomposite. (k).
