Get Price2013-8-1 · A dendrimer-ultrafiltration system was designed to recover metal ions from aqueous solutions (Diallo et al., 2005). The system achieved almost complete removal of Cu 2+ ions with initial concentration of 10 ppm and Cu 2+ to PAMAM dendrimer-NH 2 ratio of 0.2. After adsorption, the metal ion laden dendrimers were recovered by ultrafiltration and regenerated by decreasing pH to 4.
