摘　　要：制备了ZrO2纳米粉体,并使用硅烷偶联剂处理得到乙烯基二氧化锆。通过自由基聚合,苯乙烯、二乙烯基苯与二氧化锆颗粒表面乙烯基反应,将交联聚苯乙烯包覆在锆胶表面上,再经硫酸磺化,制得聚合物/氧化锆阳离子交换固相萃取柱填料。采用FT-IR和TEM手段表征了合成材料的组成与结构。通过固相萃取与高效液相色谱联用测定了水溶液中磺胺甲基嘧啶和磺胺二甲基嘧啶,考察了该固相萃取小柱的吸附性能及测试方法的可靠性,结果令人满意。In this paper, zirconia powder synthetized was treated by vinyl-silane coupling agent to get vinyl modified zirconia.The SPE packing of cross-linked polystyrene encapsulated zirconia-base was synthesized by styrene,divinylbenzene and vinyl-modified zirconia in radical polymerization. The polystyrene encapsulated zirconia-based was sulfonated by concentrated sulfuric acid and the cation exchange packing of for solid phase extraction was prepared.The composition and structure of the meterial were characterized by FT- IR, SEM and XRD.The reliability of detection method and adsorption properties of SPE columns were investigated by detecting the content of the sulfamerazine and sulfamethazine in the water on basis of SPE-HPLC, and the results were satisfied.
