Abstract
A study has been made of scandium distribution between neat tributyl p hosphate (TBP) and 0.2-1.2 M scandium solutions in 2.7-12.3 M nitric a cid. Scandium extracts in equilibrium with 0.2-1 M Sc in 6-12 M HNO3 c ontain from 2 to 5 HNO3 molecules per scandium atom in extracted Sc co mplex.
