摘要
氢化物与硝酸银反应形成银溶胶的分光光度法,具有操作简便、分析速度快、灵敏度高和应用范围广等特点,深入探讨银溶胶的物理和化学性质对改进此方法的实验条件,增强银溶胶的稳定性和改善方法的重现性,以及提高方法的灵敏度和选择性等都有重要的意义,我们以铅烷与硝酸银的反应产物为研究对象,用X光小角散射仪。
In this paper, the characteristic of the reaction between product covalent hydrides and silver ion is discussed, and their effect in spectrophotometry is presented. By experiments, the properties of silver-collosol is researched, and the radius of colloidal silver is calculated. The property of loading charge of colloidal silver and the action of colloid protectant are confirmed. These results are of great importance to improve spectrophotometry which relate to silver-collosol.
