Preparation and coordination with Hg(II) of sulfur- and 2-amino-pyridine-containing chelating resin

A novel chelating resin anchoring 2-amino-pyridine on macroporous crosslinked polystyrene beads via a sulfur-containing spacer (PVBS-AP) has been synthesized and its structures were characterized by FTIR, scanning electron microscopy, porous structure analysis, and elementary analysis. The results of scanning electron microscopy and pores analysis demonstrated that PVBS-AP resin had meso-macro porous structure. Its adsorption properties for Hg(II), Pd(II), Ni(II), Cu(II), Zn(II), Pb(II), and Cd(II) were investigated. Some factors affecting the adsorption of PVBS-AP resin for Hg(II), such as temperature, contact time, ion concentration, and pH were also studied. The results showed that the increasing of temperature was beneficial to adsorption and Langmuir model was much better than Freundlich model to describe the isothermal process. PVBS-AP resin had good adsorption selectivity for Hg(II). It could selective adsorb Hg(II) from such binary ions system as Hg(II)-Ni(II), Hg(II)-Zn(II), and Hg(II)-Pb(II), their selective coefficients are αHg/Ni = ∞, αHg/Zn = 28.1, αHg/Pb = ∞, respectively. Five adsorption–desorption cycles demonstrate that this resin were suitable for reuse without considerable change in adsorption capacity. POLYM. ENG.
