COBALT 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 ...
متن کاملFlow-injection electrochemical determination of citric acid using a cobalt(II)-phthalocyanine modified carbon paste electrode.
The electrocatalytic activity of cobalt(II)-phthalocyanine immobilized in a carbon paste electrode for citric acid oxidation under a diffusion-controlled electrochemical process was employed to develop a selective flow injection amperomettric analysis method. Under optimized conditions, rapid and reliable determinations of citric acid (65 samples per hour) were achieved for analyses of commerci...

متن کاملA New Electrochemical Sensor for Determination of Zolpidem by Carbon Paste Electrode Modified with SnS@SnO2NP
Zolpidem is a drug that is easily attached to the GABA receptors in the brain. This property makes it very effective for tranquilizing as well as hypnagogia. According to the advantages of electrochemical analysis like high selectivity, high sensitivity, low concentration of analyte, cost-effective, portable and easy-to-use setup, they gained high amount of attention among scientists for determ...
متن کاملVoltammetric determination of cysteine at a carbon paste electrode modified with Cu(II)-salen complex
The electrochemical behavior of a modified carbon paste electrode (MCPE) with N,N′ethylenbis(salicylideneiminato)copper(II) complex ([Cu(II)-Salen]) was investigated as a newsensor for cystein. The Britton-Robinson buffer with pH 5, 10% modifier in electrode, potentialscanning rate of 20 mVs-1 and puls height of 50 mV were used as the optimum condition for thedetermination of cysteine using car...
