Abstract—

New water-soluble SeS₂ containing nanocomposites are obtained via ion-exchange interaction between selenous acid and ammonium sulfide in water using natural arabinogalactan and starch polysaccharides as nanoparticle stabilizers. The transmission electron microscopy, X-ray diffraction analysis, and dynamic light scattering data show that nanocomposites are formed as spherical crystalline SeS₂ nanoparticles 5–140 nm in size, dispersed in polysaccharide matrices. The type of stabilization matrix and ratio of reactants have a decisive influence on the nanomorphological properties of the materials obtained.

多糖阿拉伯半乳聚糖和淀粉基质中硫化硒纳米颗粒的合成

摘要——

使用天然阿拉伯半乳聚糖和淀粉多糖作为纳米颗粒稳定剂，通过亚硒酸和硫化铵在水中的离子交换相互作用，获得了新型水溶性 SeS ₂纳米复合材料。透射电子显微镜、X 射线衍射分析和动态光散射数据表明，纳米复合材料形成为大小为 5-140 nm 的球形结晶 SeS ₂纳米颗粒，分散在多糖基质中。稳定基体的类型和反应物的比例对所得材料的纳米形态特性有决定性影响。
