Paper Title:
Design of artificial chloroform Bulk Liquid Membrane (BLM) filled with supramolecular receptors and its application in selective transport of valine and leucine amino acids
A new series of receptors were designed and synthesised by the reported methods and characterised by melting point, TLC, elemental analysis, IR, 1HNMR, C13NMR, and LCMS Mass spectrometry. These synthetic supramolecular receptors were used as carrier for transport of various amino acids (Glycine, Valine, Leucine, and Proline through chloroform bulk liquid membrane system. Liquid –liquid extraction studies were performed to understand the stability of receptor- amino acid complex. The basic fundamental parameters including amino acid concentration, effect of solvent, pH of the feed/source phase, acid, base and salt concentration in the strip/receiving solution, receptor concentration in the membrane phase, rate of stirring and effect of time was studied.
The optimum concentration of amino acid for transport is 1 × 10−1 M and for receptor is 1 × 10−4 M. Transport of amino acid was not affected by the presence of salts such as sodium chloride and sodium sulphates in feed solution.
The observed trend for the extraction of amino acids by these receptors is valin>leucine>glycine (Table 1). The results reveals that receptor J1& J2 both extract valine at greater extant while release/transport less (table 2). Structure of receptor affected the extraction and transport phenomena. Receptors J1, J2 possess (Scheme1) tri and diethylene glycol chain length and rigid azo napthyl end groups. Therefore It is suggested that these receptors ( J1-J2) interact with amino acids by hydrogen bonding between –NH4+ moiety of amino acid and donor oxygen sites of the receptor.The extraction of amino acids observed also follow the sequence of hydrophobicity scale i.e. valine >Lucine >glycine.
No detectable amount of Extraction and transport of amino acids were not observed by Receptor J3 and J4.Those are used as such as receptor .Molecular tailoring/designing of receptor is fruitful for better selectiveness.
The receptors (J5 and J6) are better carrier for valine and leucine amino acids due to weak interactions of naphthyl side arm with amino acid.Selective transport of valine and leucine is observed and the percentage of valine and leucine transported through receptor bearing chloroform liquid membrane after 24 Hours was 88 ± 0.1%.nd 69 ± 0.1% respectively.
