摘　　要：采用化学共沉淀法制备亲油性Fe_(3)O_(4)微粒,通过TEM、XRD、FTIR等分析方法对纳米Fe_(3)O_(4)粒子进行表征。通过改变Fe^(2+)和Fe^(3+)摩尔比、反应温度、反应时间3个反应条件,分析对纳米Fe_(3)O_(4)粒子粒径的影响。结果表明,当Fe^(2+)和Fe^(3+)摩尔比为26∶50、反应温度为85℃、反应时间为30min时,纳米Fe_(3)O_(4)粒子粒径最小,为22.3nm。Lipophilic Fe_(3)O_(4)particles were prepared by chemical co precipitation method,and the nano Fe_(3)O_(4)particles were analyzed by TEM,XRD,FTIR and other analytical methods.By changing the molar ratio of Fe^(2+)and Fe^(3+),reaction temperature,and reaction time,analyze the effects of these three reaction conditions on the particle size of Fe_(3)O_(4)nanoparticles.The results showed that when the molar ratio of Fe^(2+)and Fe^(3+)was 26∶50,the reaction temperature was 85℃,and the reaction time was 30min,the particle size of Fe_(3)O_(4)nanoparticles was the smallest,which was 22.3nm.
