摘　　要：以反应性SiO2和壳聚糖为原料,用环氧氯丙烷作交联剂,制得了一种新型的SiO2/壳聚糖纳米颗粒。产品结构经红外光谱(FT-IR)、透射电镜(TEM)和X-射线能谱(EDS)表征;用制备的纳米颗粒对苯酚进行吸附性能测试。结果表明,壳聚糖与反应性SiO2通过环氧氯丙烷桥连为一个高分子聚合物,制得的新型SiO2/壳聚糖纳米颗粒的粒径为100～300nm,比壳聚糖具有更好的苯酚吸附性。A novel SiO2 /chitosan nanoparticles was obtained by reactive SiO2 and chitosan as raw material,and epichlorohydrin as cross-linking agent.The structures of pruducts were characterized by FTIR,TEM and EDS.Phenol was used to test adsorption properties of the nanoparticles.The results showed that macromolecules was synthesized with chitosan and reactive SiO2 through the bridge of epichlorohydrin,obtained nanoparticles size was 100-300nm,and the nanoparticles had more effective adsorption of phenol than chitosan.
