采用固/液界面溶剂溶胀诱导相分离法，对磺化聚苯乙烯（ SPS）和表面负载有生物相容性的壳聚糖（ CS）的核壳型SPS/CS两种微球进行溶蚀，制备出具有多孔结构的SPS和SPS/CS微球。研究发现，溶剂类型和醇水比是影响多孔聚合物微球形态的主要因素。利用透射电镜（ TEM）对多孔微球的结构进行表征，通过紫外可见分光光度计（ UV-Vis）测定SPS/CS多孔微球在室温环境下对Cr3+的吸附行为。结果表明，界面溶蚀法可制备出形貌均一的多孔聚合物微球，其对Cr3+吸附量明显优于实心结构的微球。

Sulfonated Polystyrene( SPS)microsPheres were used as temPlates and core-shell SPS/CS mi-crosPheres were PrePared by adsorbing chitosan onto the SPS surface via electrostatic interaction between amino and sulfoacid grouPs. Porous structured SPS and SPS/CS microsPheres were PrePared by solvent/nonsolvent induced Phase seParation method. Transmission electron microscoPy( TEM)was used to ob-serve the microstructure and the Cr3+ adsorPtion behavior was characterized by UV-Vis at room temPera-ture. The results indicated that the uniform morPhology of the Porous Polymer microsPheres was PrePared by interface dissolution method. And the Porous SPS/CS showed an obviously enhanced maximum adsorP-tive caPacity to Cr3+.
