Abstract:

A modified polymer, i.e. benzylated polyethyleneimine (PEI), coated on a glassy C electrode in which neg. charged quinones were incorporated, was used for voltammetric measurement of pH. A linear dependence of the av. of the peak potentials as a function of pH was obsd. The system was successfully applied also to ultramicroelectrodes. [on SciFinder(R)]
