A Tentative Anion Exchange-Precipitation Procedure for the Determination of Cs¹³⁷
An anion exchange precipitation procedure was developed for the determination of Cs¹³⁷ in various aged fission product waste solutions, and other solutions containing Cs¹³⁷. The procedure is based on the ability of an anion exchange column to function simultaneously at an anion exchanger and as a precipitating agent (1).

Wet Fluoride Studies: Calcium Plutonium (IV) Fluoride
Laboratory studies have shown that the double salt, CaF2-PuF4, can be precipitated by rapid addition of hydro-fluoric acid to solutions containing 25 to 75 g Pu/1, caleium equimolar to plutonium, and 1 to 10 M HNO3. The precipitate, which is subsequently washed with water and dried to 300 degrees C in dehumidified, deoxygenated argon, can be reduced thermally by calcium to give high yields of plutonium metal.
