抗癌药物载体——磁流体的制备及其性质研究

Study on factors affecting the preparation and property of magnetic fluids for anticancer pharmaceuticals

实验表明磁流体的磁化强度与制备过程中Ｆｅ２＋与Ｆｅ３＋的摩尔比、沉淀时的ｐＨ值、熟化温度等条件有密切的关系。此外，氢氧化钠溶液的加入方式、搅拌速度、包封温度、包封时间、油酸钠的用量，中和时的ｐＨ值等诸因素对磁化强度也有一定的影响。本文在考虑上述诸因素影响的基础上，得出了磁流体的最佳制备条件，同时对磁流体的一系列物理性质如：磁化强度、沸点、蒸发热、稳定性等进行了测试和讨论。

The magnetic property of magnetic fluids prepared by chemical co precipitation is closely related to the mixing process of precipitators,the concentration of the solution and the molar ratios of Fe 2+ /Fe 3+ ,ect.We have improved the method of the chemical co precipitation and found that there is an obvious increase in the magnetization.
