以十二烷基硫酸钠为表面活性剂形成胶束，采用微乳液法制备磁性CoFe2O4尖晶石铁氧体纳米颗粒。利用因子设计的统计方法，建立了一系列综合实验的数学模型。该化学计量模型定量地将纳米颗粒的大小与实验条件联系起来。结果表明，在5 ~ 35 nm的范围内，该方法可以预测纳米颗粒的平均直径，精度为1 ~ 3 nm。纳米颗粒尺寸与合成条件之间的定量相关性为选择控制纳米颗粒尺寸的实验条件提供了理论依据。
Magnetic CoFe2O4 spinel ferrite nanoparticles are synthesized by a microemulsion method using sodium dodecyl sulfate as the surfactant to form micelles. A statistical method of factorial design is used to establish a mathematical model from a series of synthesis experiments. This chemometric model quantitatively correlates the size of the nanoparticles with the experimental conditions. It has demonstrated the capability of predicting the mean diameter of nanoparticles from the synthesis conditions with a precision of 1−3 nm over a range from 5 to 35 nm. This quantitative correlation between the size of nanoparticles and the synthesis condition provides the rationale for choosing experimental conditions to control the nanoparticle sizes.
