Abstract	The extraction abilities and the transport through chloroformliquid membrane of p-tertbutylcalix[n]arenes (n = 6, 8)upon some amino acid methylesters have been investigated.The experimental results suggested that amino acidmethylesters are extracted into organic phase andtransported by p-tert-butylcalix[n]arenes (n = 6, 8)in the presence of tropaeolin 00([4-(4'-anilinophenylazo)benzenesulphonic acid]) ascounterion. The extractability and the transport havebeen proved to be essentially controlled by the structureof calixarene, the nature of amino acid and the natureof anion used as ion pair for cation-receptor complexes.Also, the results suggested that there is no relationshipbetween the extraction efficiency and the hydrophobicityof amino acid esters. The results suggest furtherpossibilities for optimal separation of amino acidsderivatives and other biological species.
