中文摘要	as a green process, electrochemistry in aqueous solution without a supporting electrolyte has been described based on a simple polyelectrolyte-functionalized ionic liquid (pfil)-modified electrode. the studied pfil material combines features of ionic liquids and traditional polyelectrolytes. the ionic liquid part provides a high ionic conductivity and affinity to many different compounds. the polyelectrolyte part has a good stability in aqueous solution and a capability of being immobilized on different substrates. the electrochemical properties of such a pfil-modified electrode assembly in a supporting electrolyte-free solution have been investigated by using an electrically neutral electroactive species, hydroquinone ( hq) as the model compound. the partition coefficient and diffusion coefficient of hq in the pfil film were calculated to be 0.346 and 4.74 x 10(-6) cm(2) s(-1), respectively. electrochemistry in pfil is similar to electrochemistry in a solution of traditional supporting electrolytes, except that the electrochemical reaction takes place in a thin film on the surface of the electrode. pfils are easily immobilized on solid substrates, are inexpensive and electrochemically stable. a pfil-modified electrode assembly is successfully used in the flow analysis of hq by amperometric detection in solution without a supporting electrolyte.
