Description
Perchlorates of Sc3+, Y3+, La3+, and Eu3+ have each been extracted from 0.1 mol dm-3 aqueous solution of μ=1 with trioctylphosphine oxide (TOPO) in hexane. The hydration number of the extracted salts has been determined by Karl Fischer titration. Sc3+, Y3+, and Eu3+ are extracted as the tetra- and hexa-solvates of TOPO but the assumption of octa-solvate on addition to the tetra-solvate explains the extraction data of La3+ well. The hydration number of tetra-solvates is 2 (Sc3+ and Eu3+), 3 (Y3+) and probably 4 for La3+ ion. That of hexa-and octa- solvates is 4-5. (author). 1 tabs
