分别以聚苯乙烯微球和氯乙酰化聚苯乙烯为原料改性修饰了表面基团、臂长、结构功能各异的3种聚合物微球，并对修饰结果进行红外和扫描电镜分析。结果表明，修饰之后的微球依然保持较好的球形度、结构和形态均匀。研究了3种聚合物微球对拟除虫菊酯类农药的吸附能力。结果表明，改性之后的聚合物微球吸附能力优于原料微球。为农药残留聚合物固相萃取材料的开发奠定了理论基础。

Three kinds of polymer microspheres with different surface group,structure,length of the arm and polarity were modified with polystyrene microspheres and chloroacetyl polystyrene as the raw materials,and then charactered by infrared spectrometer and scanning electron microscopy.The results showed that the sphe-ricity,structure and form of polymer microspheres were well remained after modification.Finally,the adsorp-tion abilities of three kinds of polymer microspheres on pyrethroid pesticides were studied.The results showed that the adsorption abilities of the polymer microspheres after modified were better than the raw microspheres. The experimental results lay a theoretical foundation for the development of solid phase polymer extraction ma-terial of pesticide residues.
