Abstract
Chelation with bio-polymers is recognized as an emerging technique for the treatmente os wastewater containing heavy metals. In a first step of this study, the chelatmg kinetics of bio-polymers as alginic acid, calcium alginate, carrageenan and chitosan in relation with the Cu(II) at different pH and metal concentration, has been investigated. The chitosan was crosslinked with different chemicals and at different concentrations, to improve its stability at several pH. The used technologies for the regeneration of each polymer were ionic exchange and electrodeposition. Only with a combination of both technologies has been possible to obtain values of regeneration up to 95%.
