The removal of heavy metals from aqueous solutions by sawdust adsorption - removal of lead and comparison of its adsorption with copper

摘要

In this work, sorption of lead on sawdust (SD) has been studied by using batch techniques. Similar to the sorption of copper, the equilibrium sorption levels for lead is a function of the Solution pH, contact time, sorbent and sorbate concentration. The equilibrium adsorption capacity Of sawdust for lead was measured and extrapolated using linear Freundlichk and Langmuir isotherms And compared with that for copper.
