• 中文摘要： Poly(styrene/divinyl benzene) with cryptand 22 as an anchoring group was synthesized and applied as a bifunctional packing material for the separation of both cations and anions. At pH<2, the resin can be protonated and applied as an anion exchanger for the separation of anions; with water as eluent, inorganic anions such as F/sup -/, Cl/sup -/, Br/sup -/, NO/sub 3//sup -/, I/sup -/ were well separated. After deprotonation at pH>10, the resin became a cation exchanger and successfully separated alkali metal ions such as Li/sup +/, K/sup +/ and Cs/sup +/ with methanol as eluent. The effects of solvents, flow rate and temperature on the separation of various ions were also investigated.
