摘　　要：采用微波辅助加热法制备铁尖晶石MFe2O4(M=Co2+、Zn2+)纳米粒子,通过粉末X射线衍射、红外光谱和氮气吸附/脱附技术对合成样品进行表征。结果表明:铁酸钴比表面积为42.3 m2/g,铁酸锌比表面积为17.4 m2/g;丁基黄药在铁尖晶石表面的吸附行为均为多分子层吸附,符合BET吸附类型,且丁基黄药对铁酸钴表面亲和力大于铁酸锌。Spinel ferrite MFe2O4（ M=Co^2＋、Zn^2＋） nanoparticles were successfully prepared by microwave-assisted heating method,and systematically characterized by powder X-ray diffraction（ XRD）,Fourier transform infrared spectroscopy（ FTIR） and nitrogen adsorption/desorption analysis methods. The results showed that CoFe2O4 spinel has the specific surface area of 42. 3 m^2/ g,and ZnFe2O4 spinel has the specific surface area of 17. 4 m^2/ g. The adsorption behavior of butyl xanthate on spinel ferrite MFe 2O4（ M = Co^2＋、Zn^2＋） surface is multilayer adsorption and belongs to BET adsorption model. Butyl xanthate has better affinity on the surface of CoFe2O4 than ZnFe2O4.
