Abstract:

The present study deals with the preparation and characterization of zinc oxide for adsorption characteristics of methyl orange (MO). The influence of initial dye concentration, contact time and adsorbent dose on the adsorption capacity were investigated. The equilibrium adsorption was analyzed using Langmuir and Freundlich adsorption models. In order to study the kinetic aspects of the adsorption of MO, pseudo-second order were employed. The results confirm the feasibility of ZnO adsorption process of MO.
