Abstract
A cross-linked polymer composed of polyethylenimine reacted with 1,4-dibromobutane coated on a glassy carbon electrode and containing negatively charged ions, Fe(CN)36/4“, is proposed as a reference electrode in organic solvents. The system exhibits a relatively stable potential (±10 mV) over a period of several days in acetonitrile and a reasonable potential stability for several hours in N, N’-dimethyl-formamide and dichloromethane. The different parameters that affect the behavior of the GCE/PEI/Fe(CN)3 6 /4“ are characterized.
