The newspaper describes a absorption of argentiferous descent with Impregnated Resins braced by adsorption of a bifunctional extractant, O-methyl-dihexyl-phosphine-oxide O’-hexyl-2-ethyl phosphoric acid (BL) into polymeric macroporous supports of Amberlite XAD2-type (XAD2-BL). The derivation of these metal ions involves the arrangement of blended metal money in the resin phase with a all-purpose composition ML.
