Abstract

This work is devoted to studying the structural and morphological properties of a silver colloidal solution obtained by the method of electrical-spark discharge in distilled water. Silver nanoparticles are formed as a result of metal sputtering from the surfaces of silver electrodes, between which a high-voltage electric discharge is generated. The solution is stabilized by forming a layer of anions around the nanoparticles. The structural characteristics of the colloidal solution are studied by small-angle X-ray scattering and transmission electron microscopy. The ionic composition is determined qualitatively using electrospray ionization mass spectrometry, while silver concentration is measured by inductively coupled plasma atomic emission spectrometry.

通过电火花放电获得的银纳米粒子胶体溶液的结构特征和离子组成

摘要

这项工作致力于研究在蒸馏水中通过电火花放电方法获得的银胶体溶液的结构和形态特性。由于金属从银电极的表面溅射而形成银纳米颗粒，在银电极之间产生高压放电。通过在纳米粒子周围形成一层阴离子来稳定溶液。通过小角度 X 射线散射和透射电子显微镜研究胶体溶液的结构特征。离子组成使用电喷雾电离质谱进行定性测定，而银浓度通过电感耦合等离子体原子发射光谱测定。
