Description	Cyclic voltammetry is used to investigate the transfer of heparin polyion across the interface between water and the ionic liquid (IL) membrane composed of tridodecylmethylammonium cation (TDMA+) and tetrakis[3,5-bis(trifluoromethyl) phenyl]borate anion (TFPB). Study reveals a tunable effect of the semihydrophobic tetraalkylammonium cations (TAA+) present at trace concentrations in the aqueous solution containing heparin. Theoretical considerations based on the mixed-potential concept and experimental evidence suggest that the TAA+ cations promote the extraction of heparin into the IL phase, from which heparin can be stripped off by applied potential providing a well-separated current signal. A new method for the amperometric detection of heparin is proposed.
