Calix[6]arene, Membrane, Transport experiment, Polymer inclusion membrane
Calix[6]arene having both carboxylic acid (1,3,5-) and carboxamide (2,4,6-) in an alternative way was synthesized. Transport rates of alkali and alkaline-earth metal ions were tested in bulk liquid membrane and polymer inclusion membrane. Ba2+ ion was found to give the highest transport rate among tested metal ions in both BLM and PIM systems. In PIM system, high durability (longer than 30 days) of the membrane was observed.
