The extraction of Nd(III) with di-isodecylphosphoric acid was studied and compared with that by di(2-ethylhexyl)phosphoric acid. DIDPA possesses higher D<SUB>f</SUB> values in a strong acid medium but poorer separation factors against lanthanoids(III) than that of DEHPA. Mono(2-ethylhexyl)phosphoric acid increased extraction of Nd(III) with DIDPA in a similar manner as in the case of DEHPA, by a factor of D<SUB>f</SUB> of 10<SUP>3</SUP>.<BR>The extraction of Sr(II) was also investigated with DIDPA, which showed a maxi-mum of D<SUB>f</SUB> at pH 5.0. Results showed that DIDPA is a promising extractant for the partitioning of the high level liquid waste.
