| Extraction of an ion associate of the fluoride complex of aluminium and astraphloxine from aqueous solution by benzene with admixtures of polar and non-polar organic solvents has been investigated. The influence of the molar surplus of astraphloxine on the optical density of the associate for a mixed extractant consisting of benzene and nonyl alcohol has been studied as well as the influence of water phase acidity. The composition of the ion associate has been determined. |
