Facile Synthesis of Ag/ZnO Nano composites Using Fruit Peels and their Possible Applications

This research work describes the synthesis of Ag-ZnO nanocomposites by combustion method using citrus clementina peels as an effective adsorbent material for removal of dyes. Water is an essential element for life. However, critical environmental issue of 20th century is water scarcity. Water has a wide-ranging effect on all aspects of human life, a serious hazard to public health and stability of food chain. Due to human activities the waste from our industrial, agricultural, and daily activities frequently pollutes the water. Therefore, there is an urgent need to develop cost effective and sustainable technologies for the removal of contaminants from waste water. The synthesized nanocomposites were characterized by (FTIR), UV Visible, (XRD) and (SEM). Then tested their potential toward efficient removal of Eosin Y and Congo-Red from waste water by using cost effective Adsorption method. Different parameters i.e., Dosage, Time, Concentration, pH and temperature have been studied. During Linear adsorption isotherm Langmuir and Temkin isotherms are best fitted on the adsorption of Dyes. Thermodynamic and kinetic studies have also done, while Pseudo 2nd order kinetic model showed better agreement as compared with other kinetic models. Thus synthesized Ag-ZnO Nanocomposites confirmed as excellent adsorbent material for waste water treatment.
