Electrochemical Sensor for Tryptophan Determination Based on Copper-cobalt Hexacyanoferrate Film Modified Graphite Electrode
In this work, the development of a tryptophan sensor and its application to milkare described. The mixed metal (copper and cobalt) hexacynoferrates are electrodepositedon the graphite electrode, and this film exhibits an electrocatalytic activity towards for theoxidation of tryptophan. The experimental conditions, including the scan cycles, the ratio ofcopper(II) and cobalt(II), pH value, appli...
متن کاملNon-enzymatic Amperometric Glucose Biosensor Based on Copper Hexacyanoferrate-film Modified-gnp-graphite Composite Electrode
A non-enzymatic amperometric glucose biosensor based on a modified electrode was fabricated by electrochemical derivatization of copper hexacyanoferrate (CuHCF) film at gold nanoparticles (GNP) adsorbed graphite wax composite electrode. The modified electrode was characterized by cyclic voltammetry and electrochemical impedance spectroscopy (EIS). The electrode was also characterized by scannin...
متن کاملEfficient Determination of Butylated Hydroxyanisole Using an Electrochemical Sensor Based on Cobalt Oxide Nanoparticles Modified Electrode
A simple and reliable electrochemical sensor based on cobalt oxide nanoparticles modified glassy carbon electrode (GCE/CoOxNPs) for determination of butylated hydroxyanisole is presented here. The nanoparticles were fabricated by electrodepositing method. The modified electrode shows excellent catalytic activity toward butylated hydroxyanisole oxidation in pH 12.0 phosphate buffer solution (PBS...
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...
