[ 1 ] - Flow-Injection Amperometric Determination of Ascorbic Acid Using a Graphite-Epoxy Composite Electrode Modified with Cobalt Phthalocyanine

A flow injection method is reported for the determination of ascorbic acid based on amperometric detection, using a cobalt(II) phthalocyanine (CoPc) modified graphite-epoxy electrode. The amperometric respons was evaluated with regard to pH, ionic strength of the electrolyte, flow rate of the carrier solution, injected sample volume and conditioning time of the electrode. The limit of detec...

[ 2 ] - Voltammetric and Potentiometric Behavior of 2-Pyridinethiol, 2-Mercaptoethanol and Sulfide at Iron(II) Phtalocyanine Modified Carbon-Paste Electrode

A carbon-past electrode modified with iron(II) phathalocyanine (FePc) was used as a sensitive potentiometric sensor for determination of 2-pyridinethiol (2PT). 2-mercaptoethanol (2ME) and sulfide ion in aqueous solutions. The modified electrode acts as an electrocatalyst for oxidation of these compounds, and lowers the overpotential for oxidation reactions by more than 400 mV, compared to t...
