N2 - The synthesis of surface-functionalized polymer nanoparticles for selective sequestering of heavy metals, is demonstrated. A block-copolymer particle consisting of a polystyrene (PSTY) core and a thin shell of poly(2-acetoacetoxy) ethyl methacrylate) (polyAAEMA) was synthesized. Metal binding experiments with Co2+ and Hg2+ metal ion solution doped with Co-57 and Hg-197/Hg-203, respectively, in the presence of a thin layer of polyAAEMA and a product of dialysis of polyAAEMA were undertaken. The results show that the reverse addition-fragmentataion chain transfer (RAFT) end groups on the surface particles can be utilized to control the molecular weight and particle morphology, and also selectively bind to Hg, Pb and Co.
