title: Okadaic acid and its interaction with sodium, potassium, magnesium and calcium ions: complex formation and transport across a liquid membrane.
abstract: Okadaic acid, a macrocyclic polyether compound, was shown to mediate the transfer of Na+, K+, Mg2+ and Ca2+ ions from aqueous solution to an organic phase, with a preference for Na+ ions. A kinetic study of the transport of these ions across a liquid membrane showed that the Na+ ion was more rapidly transported than the other ions and that the Na+ ion flux was dependent on the okadaic acid concentration.
