Abstract The extraction of HNO3, TcO 4 − , and Pd by solutions of dibutyl N,N-diethylcarbamoylmethylenephosphonate (DBDECMP) and dibutyl N,N-diethylcarbamoylphosphonate (DBDECP) in CCl4 has been studied. At low aqueous acidities, HNO3 is extracted by both extractants (S) as HNO3·S and HNO3·S2, at 〉1M HNO3 only HNO3·S is formed. The distribution of TcO 4 − and Pd(II) is nearly independent of HNO3 concentration. A second power dependence on extractant concentration was found for the extraction of Pd(II) by DBDECMP and TcO 4 − by DBDECP, and a 4th power dependence for TcO 4 − -DBDECMP.
