Electrochemical Sensor for Determination of Ascorbic Acid Using a 2-Chlorobenzoyl Ferrocene/Carbon Nanotube Paste Electrode
A chemically modified carbon paste electrode with 2-chlorobenzoyl ferrocene (2CBF) and carbon nanotube (2CBFCNPE) was employed to study the electrocatalytic oxidation of ascorbic acid in aqueous solution using cyclic voltammetry, square wave voltammetry and chronoamperometry. The diffusion coefficient (D = 1.42 × 10-6 cm2 s-1), and the kinetic parameter such as ...
متن کاملCOBALT PHTHALOCYANINE MODIFIED CARBON PASTE ELECTRODE AS A POTENTIOMETRIC SENSOR FOR DETERMINATION OF ASCORBIC ACID
A carbon Paste electrode modified with cobalt (II) phthalocyanine (CoPC) was used as a sensitive potentiometric sensor for determination of ascorbic acid in aqueous solutions. The potential response of the electrode is a linear function of ascorbic acid concentration over the range 5 10 to 10 M (?1- 1800 µg ML ) with a Nernstian slope of 56 mV at pH 7. The limit of detection was 0.2 µg ...
