Abstract
Several lipophilic N-[2-hydroxyimino-2-(pyridin-2-yl)ethyl]trialkylammonium salts 1 were synthesized from the corresponding oxo compounds and hydroxyl amine in the presence of Ni2+ ions which stabilize the oximes by chelation. Salts 1 are surfactants possessing a powerful chelating subunit. Their abi lity to extract different metal ions from aqueous solutions into organic so lvents was tested by metal ion transport through a liquid membrane. (C) 199 9 Elsevier Science Ltd.
