Adsorption analysis of Pb(II) by nanocomposites of chitosan with methyl cellulose and clay

摘要: Chitosan is the one of most abundant natural biopolymers after cellulose. The chitosan was converted into nanoparticles and to improve adsorption efficiency, polymers kaolin clay methyl cellulose has been mixed separately form binary composites NC+MC NC+KC. prepared were characterized. Batch process carried out effects various parameters influencing Pb(II) such as initial concentration metal solution, pH, contact time adsorbent have studied. data obtained from used fit in Langmuir Freundlich isotherms. Adsorption kinetics applied evaluate order followed by process. second kinetic model found correlate well with experimental data. Both follow model.
