Extraction of ternary complexes of thorium(IV) with 3-phenyl-4-benzoyl-5-isoxazolone and neutral donors from nitric acid medium
The extraction behaviour of thorium(IV) from aqueous nitric acid employing 3-phenyl-4-benzoyl-5-isoxazolone (HPBI) in the presence of tri- n-octyl phosphine oxide (TOPO) as well as tri- n-butyl phosphate (TBP) in xylene medium was investigated.

| description | The extraction behaviour of thorium(IV) from aqueous nitric acid employing 3-phenyl-4-benzoyl-5-isoxazolone (HPBI) in the presence of tri-
n-octyl phosphine oxide (TOPO) as well as tri-
n-butyl phosphate (TBP) in xylene medium was investigated. The extraction constant (log
k
ex) for the binary organic phase species Th(PBI)
4 was determined to be 8.26 which is by far the largest amongst the corresponding values known for other
β-diketones. The overall extraction constant (log
K) for the ternary species Th(PBI)
4 TBP and Th(PBI)
4·2TOPO were estimated to be 14.96 and 20.96 respectively. An inverse correlation of the adduct formation constant (log
K
s) with the p
K
a of the
β-diketones, 2-thenoyltrifluoroacetone, 1-phenyl-3-methyl-4-benzoyl-5-pyrazolone and HPBI, was observed. The steric as well as the electronic effects of adduct formation have been discussed. Analytical application of HPBI for the separation of
234Th radiotracer from natural uranium (99.3%
238U) has been suggested. |
