Adsorption of lead (Pb) from aqeuous solution by Fe(III)-modified chitosan microspheres (ICS)

The Fe(III)-modified chitosan microspheres (ICS) were prepared for Pb removal from aqueous solution. The effects of initial concentration, contact time, beads dosage, pH and temperature for Pb adsorption were investigated. The maximum adsorption capacity is found at pH 5 during the pH studies, and t...
