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 کاملAn electrochemical acetaminophen sensor based on La3+/Co3O4 nanoflowers modified graphite screen printed electrode architecture
In this study, the La3+/Co3O4 nanoflowers were synthesized by co-precipitation method. The morphology of the La3+/Co3O4NFs were characterized using scanning electron microscopy (SEM), and were further used to modify the graphite screen printed electrode (GSPE). The electrochemical behavior of acetaminophen at La3+/Co<s...
متن کاملA New Sensor Based on Graphite Screen Printed Electrode Modified With Cu-Nanocomplex for Determination of Paracetamol
Paracetamol is a non-steroidal anti-inflammatory drug used as an antipyretic agent for the alternative to aspirin. Conversely, the overdoses of paracetamol can cause hepatic toxicity and kidney damage. Hence, the determination of paracetamol receives much more attention in biological samples and also in pharmaceutical formulations. Here, we report a rapid<span id="transmark" style="display: non...
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...
