Abstract
A Mossbauer effect method was used to study the formation of mixed hydroxid es in the alkaline coprecipitation of Pu(IV) or ND(IV) with Fe(III). The Mo ssbauer spectra of mixed Pu-239(IV)-Fe(III) and Np-237(IV)-Fe(III) hydroxid e samples differ from that of pure alpha -FeO(OH) formed in aqueous basic s olutions. Alkaline coprecipitation of Np(V) or Np(VI) with Fe(III) hydroxid es does not produce the mixed hydroxides shown by Pu(IV) or Np(IV) with Fe( III). The general Mossbauer spectral parameters of the Np(V), (VI)-Fe(III) hydroxides are similar to those of pure alpha -FeO(OH).
