Electrochemical behaviorof epinephrine (EP) at a gold electrode modified with self-assembled monolayer (SAM) of thiolactic acid (TLA) has been studied. At TLA SAM-modified electrode the cyclic voltammetric response of epinephrine was promoted. Possible reaction mechanism has been discussed. In 0.1 mol L-1phosphate buffer solution (pH 7.0) a well-defined oxidation peak of EP at 0.198 V was observed...
Glassy carbon electrode (GCE) was modified with p-aminobenzene sulfonic acid (p-ABSA) film electropolymerised in 0.1 mol L NaCl solution by cyclic vollammetry (CV). Modified electrode showed excellent electrocatalytical effect on the oxidation of epinephrine (EP). In phosphate buffer solution (PBS) of pH 7.0 oxidation peak current was proportional to the concentration of EP in the ranges: 1.0 x 10...
