Acilitated ions transfer by dibenzo-15-crown-5 across the water/1,2-dichloroethane interface using micro- and nano-pipets

摘要

Ion transfer across a liquid/liquid (L/L) interface, or an interface between two immiscible electrolyte solutions (ITIES) plays a significant role in many biochemical fields and technological systems. Since Taylor and Girault first demonstrated a micro-L/L interface could be supported at the tip of a micropipette, and is expected to be useful to overcome the problems for electrochemical measurements at liquid/liquid interfaces, micropipette and microhole as tools for study ion transfer across L/L interface has simulated a great deal of interest in elucidating the thermodynamic parameters and the mechanisms. Under certain experimental conditions, a glass micropipette or a nanopipette functions just like an ultramicroelectrode.
