Abstract
The influence of the concentration of ionic and nonionic organic molecules and inorganic ions on the adsorbability of Eu3+ ions on the AgBr precipitates is described. It was found that the concentration of the inorganic as well as the concentration of organic molecules in the systems has a great influence on the adsorption of Eu3+ ions. Electromicrographs show that the dispersity of AgBr precipitates strongly depends on the concentration of the nonionic organic molecules present in the systems. At higher concentration of these molecules the particles of AgBr become very small and the adsorption of Eu3+ ions increases. Adsorption equilibrium between Eu3+ ions and organic and inorganic ions has been determined. Eu3+ ions can be desorbed from the precipitates if the concentration of organic and inorganic ions are high enough.
