The extraction of Am(III) with benzyldimethyllaurylammonium nitrate from acidic nitrate solutions was studied. The effects of the kind and concentration of the salting-out agent, of the organic solvents, and of the concentrations of the other components in the extraction system on the distribution ratio values and applicability of this extracting agent to the separation of americium from lanthanoids are discussed. From the analytical data on the organic phase and from the infrared spectra, the composition of the extractable associates and their extraction mechanism were established.
