Sodium Alginate-Cellulose-Nano-Clay Composite Adsorbent Applied for Lead Removal from Wastewater

A sodium alginate/cellulose/n-clay composite was prepared as potential adsorbent for removal of Pb(II) from wastewater. The results showed that obtained adsorbent used for 4 mg L-1 initial concentration of Pb(II) in wastewater after 90 min adsorption time led to 90% removal efficiency and the adsorption capacity of the prepared composite was 0.11 mg .g-1. The isotherms and kinetics of adsorption revealed that the equilibrium adsorption and kinetics were well-described by the Langmuir model and pseudo-second-order kinetics, respectively.
