Pu(III) � Hydrochloric Acid (cont) • Reduction to Pu(III) can therefore be used to prevent uptake on the resin or for rapid elution. • Some of the reducing agents that can be added to the feed solution or the eluent are: NH 4I, HI, HBr, H 2O 2, SO 2 38
Pu � Hydrochloric Acid • In addition to these reducing agents, HCl-HF mixtures, e.g., 0.36 M HCl – 0.01 M HF, can be used for the rapid elution of plutonium. • Dilute solutions of HCl, e.g., 0.1 M HCl, can also be used for this purpose. 39
