Abstract

The extraction behavior of N,N,N',N'-tetrabutylmalonamide (TBMA) employing toluene as diluent toward Dy(III) has been investigated. The effect of the concentrations of nitric acid, lithium nitrate and extractant and also of the temperature on the distribution ratio has been studied. The stoichiometry found for the Dy(III) extracted species suggests a structure such as Dy(NO3)3 .3TBMA. An attempt has been made to establish the structure of the isolated extracted species recurring to the data of IR.
