The extraction behaviour of some trivalent elements in the Aliquate-336-1,3-diisopropyl genzene-nitric acid system has been investigated. For most of the elements a maximum in the distribution ratio occur at about 2 molar nitric acid. At 0.20 molar Aliquate-336 lanthanum attained the highest distribution ratio, about 0.05, of all investigated elements. It was found that nitric acid to a large extent influences the distribution ratio of trivalent elements since it competes with metal nitrate complexes for the extractant molecules. A first approach to a model describing the extraction system is derived.
