Abstract

Mössbauer absorption spectroscopy and X-ray diffraction analysis were used to study Fe_3 – δO₄ nanoparticles formed in the presence of natural polyelectrolytes of two types: derivatives of humic materials and low polymer chitosan. By an example of samples synthesized using either the Massart method or by in situ oxidation of metal it was shown that polyelectrolytes differing in charge and hydrophility affect mainly the morphology of Fe_3 – δO₄ particles, whereas their composition and structure depend only slightly on the polyelectrolyte nature.

天然聚电解质存在下合成的Fe 3 –δO 4纳米粒子

摘要

穆斯堡尔吸收光谱和X-射线衍射分析被用来研究的Fe _{3 - δ} ø _4个形成于两种类型的天然聚电解质的存在纳米颗粒：腐殖酸的材料和低的聚合物脱乙酰壳多糖的衍生物。通过在金属的原位氧化使用任一Massart的方法或通过合成的样品的一个例子已表明聚电解质在充电和hydrophility不同影响的Fe主要形态_{3 - δ} ø _4个颗粒，而它们的组成和结构取决于仅稍微上聚电解质的性质。
