Liquid-Liquid Extraction and Bulk Liquid Membrane Transport of Alkali Metal Ions through Various Organic Liquid Membranes Using Dipropyleneglycolmonomethylether

Abstract

Podands are major class of supramolecular hosts having the  possibility to form interesting complexes by forming pseudocyclic cavity
exhibiting extractability and selectivity by trapping the metal ions.  Dipropyleneglycolmonomethylether was used to study its carrier ability for alkali metal ions (Li+, Na+ and K+) using picrate (Pic-),  dinitrophenolate (Dnp-) and orthonitrophenolate (Onp-) salts through
various organic solvents viz. 1,2-dichloroethane, chloroform and  carbontetrachloride towards extraction and transport. Transport of Na+ exceeds than K+ and Li+. Thus, the development of the liquid-membrane  ion selective electrodes owes much to the progress of upramolecular  chemistry and has played an important role in bridging supramolecular  chemistry with analytical chemistry, material technology, medicines, green chemistry, data storage and processing etc.
