Carrier-assisted transport through liquid membrane is one of the important application of supramolecular chemistry Calix[6]arene was utilized as an extractant as well as carrier for amino acids through liquid membrane The receptor forms complex with amino acids by CH-n interactions, van der Wail's interactions and hydrogen bonding The host compound exhibited high fluxes for amino acids with high extraction efficiency i e valine and alanine due to its cyclic structure and cavity size The sequence of extraction and transport efficiency observed was valine > alanine > glycine > threonine and valine > glycine > alanine > threonine respectively In SLM experiments using cellulose nitrate, PTFE. Onion membrane and egg shell membrane support it was observed that receptor A(1) transports glycine, valine and alanine The trend of amino acid transported using PTFE and onion membrane support was glycine > alanine > valine > threonine and glycine > valine > alanine > threonine respectively Among the membrane supports used, the egg shell membrane was found better support for transport of amino acids because of its hydrophobic nature and exhibits electrostatic interactions between positively charged -H(4)N(+) group of amino acid and -COOH group of egg shell membrane These results suggest that hydrophobicity of the guest molecule plays a key role in the extraction while the structure of receptor and pH governs transport efficiency of the amino acids.
