title: Di-n-butyl carbamoylphosphonate as an extradant of inorganic ions from hydrochloric acid solutions.
abstract: The extraction of 33 elements by a 0.1M solution of di-n-butyl carbamoylphosphonate in chloroform has been investigated as a function of hydrochloric acid concentration. The results show that this new extradant readily extracts most of the elements in a high oxidation state, including the trivalent rare earths, from hydrochloric acid at concentrations greater than 6 M.
