| Abstract: | A sensitive and selective electrochemical method for the determination of epinephrine(EP) was developed using a modified carbon paste electrode(MCPE) with 2,2'-[3,6-dioxa-1,8-octanediylbis(nitriloethylidyne)]-bis-hydroquinone(DOH).Cyclic voltammetry was used to investigate the redox properties of this modified electrode at various solution pH values and at various scan rates.In differential pulse voltammetry,the modified electrode could separate the oxidation peak potentials of EP and uric acid(UA) present ... |
