抄録

Seven ω-hydroxy carboxylic acids bearing 2–5 ether oxygens with or without aromatic rings and five ω-alkoxy carboxylic acids bearing 2–6 ether oxygens with aromatic rings were employed as carriers for the active transport of alkaline earth metal ions as well as alkali metal ions through 1,2-dichloroethane or 1-hexanol as an organic liquid membrane. The relatively hydrophobic ω-hydroxy and ω-alkoxy carboxylic acids (logP>7) exhibited a high M²⁺ transport ability and selectivity over M⁺ through 1,2-dichloroethane, regardless of the number of ether oxygen. However, a marked selectivity among alkaline earth metal ions (Mg²⁺, Ca²⁺, Ba²⁺) was not observed. The less hydrophobic carboxylic acids (logP<6) did not transport Ba²⁺ through 1,2-dichloroethane. Ba²⁺ transport ability of the hydrophobic acids through 1-hexanol was lower than that through 1,2-dichloroethane. Linoleic acid in the presence of oligo- and polyethylene glycols showed efficient Ba²⁺ transport through 1,2-dichloroethane, although a long-chain fatty acid was not able to transport Ba²⁺ by itself.
