摘 要：By the suspended condensation reaction of poly（choloromethyl thiirane） with o-tolidine and o-dianisidine respectively, two new microbeads of magnetic chelating resins were synthesized by usingγ-Fe2O3 as magnetic core. Their adsorption properties for Hg（Ⅱ）, Cu（ Ⅱ ） , Zn（ Ⅱ ） , Pb（ Ⅱ ） , Au（ Ⅲ ） , Pd（ Ⅱ ） , Pt （Ⅳ ） and Ag（ Ⅰ ） were investigated. The microbeads possess excellent adsorbability for Hg（ Ⅱ） and noble metal ions, and predominantly adsorbed Pd（ Ⅱ） or Hg（Ⅱ） in the coexistence of Cu （ Ⅱ ）, Zn（ Ⅱ ） andMg（Ⅱ）. The experimental results demonstrate that resin Ⅱ with lower N and S contents has higher adsorption capacities for noble metal ions than resin Ⅰ, which shows the dianisidine group in resin Ⅱ plays an important role in the adsorption , due to the synergistic effects of methoxyl and amino group in adjacent position.
