Description of Am(III) microamount extraction in the presence of lanthanide macroamounts

On the basis of distribution dependences, an analysis of the effect of the macrocomponent (lanthanide) on the extraction of the microcomponent (americium) by benzyl-dialkylamines and benzyltrialkylammonium salts has been made. Assuming the validity of DLn=f(c Ln o ) and DAm=f(c Ln o ), the power function of the general expression log D=logP-Qlog c Ln o has been calculated, the constants have been determination of the equation applying to individual extraction systems and their physical and chemical characteristics have been discussed.
