| 摘 要： | 利用共沉淀法制备了CMS@Fe3O4磁性纳米颗粒。利用扫描电子显微镜、红外光谱、Zeta电位分析仪以及振动样品磁强计表征了纳米颗粒的形态以及性质。磁性纳米颗粒类似于球状,平均直径为(35±10)nm。结果表明,在较高的pH范围内粒子有较高的负电顺磁性。30 d后考察了CMS@Fe3O4磁性纳米颗粒的稳定性,CMS@Fe3O4磁性纳米颗粒在pH值为11时保持较好的稳定性。

| Abstract: | CMS@Fe3O4 magnetic nanoparticles were prepared by chemical coprecipitation.The morphology and properties of the nanoparticles were characterized by SEM,FT-IR,Zeta potential analyzer and VSM.The magnetic nanoparticles are quasi-spherical and with an average diameter of(35±10) nm.The results indicate that the particles have shown superparamagnetism high negative charges at the high pH range.And the stability was also investigated,after 30 d,the CMS@Fe3O4 magnetic nanoparticles remain excellent stability at pH 11. |
