In the paper, we present three different types of magnetite nanoparticles which were prepared from co-percipitation of iron (II) and (III) chlorides in aqueous solution with and without SiO2 and from thermal decomposition of iron (III) acetylacetonate in nonaqeous solutions. The obtained core-shell nanoparticles were tested in respect of their stability in distilled water, 10% acetic acid, 0.01 M citric acid, 0.9% NaCl and commercial white wine (12% of alcohol). Changes of the nanoparticles were examined by infrared spectroscopy, atomic absorption spectroscopy, transmission electron microscopy, X-ray diffraction and differential scanning calorimetry methods. Modification of magnetic properties was measured by Mössbauer spectroscopy.
在本文中，我们介绍了三种不同类型的磁铁矿纳米粒子，它们是通过在水溶液中共同沉淀铁(II)和(III)氯化物，并在有无 SiO2 的情况下，以及通过铁(III)乙酰丙酮在非水溶剂中的热分解来制备的。所得的核壳纳米粒子在蒸馏水、10%乙酸、0.01 M 柠檬酸、0.9% NaCl 和商业白葡萄酒（含 12%酒精）中的稳定性方面进行了测试。通过红外光谱、原子吸收光谱、透射电子显微镜、X 射线衍射和差示扫描量热法对纳米粒子的变化进行了检查。通过穆斯堡尔光谱测量了磁性的变化。
