| 摘 要： | 使用共沉淀法利用含有氨基的壳聚糖、含有羧基的柠檬酸钠调控合成了原位包覆的Fe_3O_4纳米颗粒,并研究了氨基与羧基在调控合成Fe_3O_4纳米颗粒方面的规律及机理.通过改变氨基、羧基的用量可实现不同尺寸Fe_3O_4纳米颗粒的可控合成.此外氨基与羧基的共同调控可合成粒度约10 nm的Fe_3O_4纳米颗粒.

| Abstract: | The chitosan and citric acid were used as additives to synthesize in-suit coated magnetite nanoparticles by coprecipitation. The influence and mechanism of amino and carboxylic groups on the synthesis of magnetite nanoparticles were studied. Magnetite nanoparticles with different granularities were synthesized by change of the additive amounts,and 10 nm magnetite nanoparticles were obtained when using amino and carboxylic groups simultaneously. |

| Keywords: | magnetite nanoparticles amino groups carboxylic groups controllable synthesis |
