摘要: The interaction of the G-2 poly(ethylene imine) dendrimer L, derived from ammonia as initiating core, with Hg(II) and HgCl4 2− was studied in aqueous solution by means potentiometric (pH-metric) measurements. Speciation these complex systems showed that L is able to form a wide variety complexes including 1:1, 2:1, 3:1 3:2 metal-to-ligand species, different protonation states, well anion ((H7L)HgCl4) 5+ ((H8L)HgCl4) 6+ . stability metal very high, making an excellent sequestering agent for Hg(II), over large pH range, promising ligand preparation functionalized activated carbons be employed remediation prevention environmental problems.
