Abstract
The adsorption of thorium has been determined on freshly prepared, coagulated sols of silver halides and silver thiocyanate. The amount of adsorbed thorium has been measured radiometrically by addition of thorium-234. It was found that the adsorption of thorium was much stronger on positively charged sols; on the negatively charged sols the adsorption was much less pronounced . The acidity also influences the adsorption, so that it is higher at greates pH values (measured up to pH = 4.5). The adsorption is nearly equal on coagulated sols of silver chloride, silver bromide and silver iodide; on silver thiocyanate is considerably less.
