| Abstract | ||
| Humic acid is used as a natural chelating polymer, so in this paper a novel method for supporting Humic acid on a rigid polyurethane foam was adopted. The cured polyurethane foam was used as a chelating polymer for the analytical study of Pb2+ , Ni2+ , Co2+ , Zn2+ and Cu2+ ions by batch method. The new foam showed an outstanding sorption for the studied ions compared to phenol formaldehyde co-polymer of Humic acid, metal ions recovery and foam regeneration was also studied using (3M) HCl as an eluant. | ||
