Abstract: 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.
