In this article we demonstrate the synthesis of the dendritic polymers and their metal ion complexation. The concept of chemoremediation in liquid homogeneous phases using polymer reagents as a green technology is presented and outlined. First, as a hydrophilic ligand, AB(3) type of dendron and its corresponding dendrimer using Poly(ethyleneoxide)-Diacid (PEO-DA) have been synthesized; second, surface of the three branched Poly(propyleneoxide)-Triamine (PPO-TA) was modified with methylacrylate and subsequently deprotected to a carboxylic acid. The dendrimers with pendant carboxylic groups were shown to be hydrolitically and termally stable. The metal complexing properties of the dendrimers were studied for Cr(III), Co(II), Ni(II), Cu(II), Zn(II), Cd(II), Pb(II) and Ag(I) ions in aqueous solution using the Liquid-Phase Polymer-Based Retention (LPR) method. In addition, the complexing capacity of synthesized PEO and PPO based dendrimers towards to Cu(II) were determined by inductively-coupled plasma spectrometry (ICP) to be 260 and 142 mgg(-1) respectively. According to the retention profiles determined as a function of filtration factor using LPR in conjunction with ICP, two and trivalent metal ions showed a strong interaction with these dendrimers (C) 2008 Wiley Periodicals, Inc.
