Sažetak
Separation of niobium and tantalum by solvent extraction
with di-n-octylami no eth anol (DOAE), di-n-octylamino propanol
(DOAP), di-n-octylamino butanone (DOAB), di-n-octylamino acetic
acid (DOAA), di-n-octylamine (DOA) and tri-n-octylamine (TOA) in
chloroform is described, in the metal concentration ra n ge of 10-5 M.
Separation can be a chieved in 0.2 M HF metal solutions in the
sulphuric acid concentration range of 1-5 M. Tantalum is extracted
into the organic phase and can be stri pped back easily with 1-6 M
hydrochloric acid. Niobium and tantalum of radiochemical purity
are obtained. The separation factors displayed by these extraction
reagents are compare d and discussed.
