摘　　要：通过种子溶胀法合成了掺杂氧化纳米金刚石的聚苯乙烯-二乙烯基苯微球(PS-DVB-OND),通过扫描电镜(SEM)和透射电镜(TEM)观察其形貌特征。考察了PS-DVB-OND和PS-DVB的耐压性,并以1,4-对苯二酚、双酚A、苯酚和叔丁基苯酚作为分析物比较了PS-DVB-OND和聚苯乙烯-二乙烯基苯(PS-DVB)作为固定相的色谱性能,最后以PS-DVB-OND为基质合成阴离子交换剂分离了F^-,Cl^-,NO2^-,Br^-,NO^-3,PO^34和SO^2-47种常规阴离子,取得了良好的分离效果。Polystyrene-divinylbenzene (PS-DVB)microsphere hybridized with oxidized nanodiamonds (PS-DVB-OND)was synthesized in this work.These particles were characterized by scanning electron microscopy (SEM)and transmission electron microscope (TEM).The meehanical stability of PS- DVB-OND and PS-DVB was tested and their chromatographic performances were investigated through separating four benzenes such as tert-butylphenol,phenol,bisphenol A and 1,4-hydroquinone.In addition,PS-DVB-OND was used as anion exchanger after modified with cationic polyelectrolyte. Inorganic anions such as F-,Cl-,NO2-,Br,NO3-,PO^3-4 and SO^2-4were baseline separated on it.
