Influence of some metal ions on the coprecipitation of Am(III) and Pu(IV) with BiPO4

The influence of increasing concentration of Na, Cs, Ca, Zn, Ni, Cr(III), La, Fe(III) and Al on coprecipitation of Am(III) and Pu(IV) with BiPO₄ has been studied. The coprecipitation of Am(III) decreases with increasing concentration of La, Fe(III) and Al and the coprecipitation of Pu(IV) decreases with increasing concentration of Cs, Fe(III) and Al. The other elements studied did not influence the coprecipitation of Am(III) and Pu(IV) with BiPO₄.
