5.9. Extraction of uranyl nitrate.
A 20 wt% solution of uranyl nitrate (UN) in water is to be treated
with tributyl phosphate (TBP) to remove 90% of the uranyl nítrte
in batchwise equilibrium contacts. Assuming water and TBP are
mutually insoluble, how much TBP is required for 100 g of solution
if, at equilibrium, (g UN/g TBP) 5.5(g UN/g H20) and: (a) all the
TBP is used at once in one stage; (b) half is used in each of two
consecutive stages; (c) two countercurrent stages are used; (d) an
infinite number of crosscurrent stages is used; and (e) an infinite
number of countercurrent stages is used?
