Monitoring the acetaminophen in biological samples and also in pharmaceutical formulations is important due to the concerns of public health care and drug safety. In this work a carbon paste electrode modified with BaTiO3 nanoparticle (BTO NPs) and room-temperature ionic liquid (IL) (n-hexyl-3-methylimidazolium hexafluoro phosphate) was fabricated. The direct electro-oxidation behavior of aceta...

In the present work, a new sensor for morphine (MO) measurement, based on modification of screen-printed carbon electrode (SPE) by using magnetic core shell manganese ferrite nanoparticles was reported. The electrochemical behaviour of MO was investigated in phosphate buffer solution (pH 7.0) by voltammetry. The electrochemical response of the modified electrode toward morphine was studied by m...

In the present work, the modified nickel electrode was electrochemically fabricated and tested for the electro-oxidation of paracetamol in alkaline media. The methods of cyclic voltammetry (CV), chronoamperometry (CA), and impedance spectroscopy (EIS) were used to determine kinetic parameters such as transfer coefficient (α), the catalytic reaction rate constants (k), and the diffusion coeffici...

To limit the nitrate contamination of ground and surface water, stimulation denitrification by electrochemical approach is an innovative way to be explored. Two reducing bio-cathodes were developed under constant polarization (-0.5 V vs SCE) using sediments water from a constructed wetland (Rampillon, Seine-et-Marne, France). The responded addition on chronoamperometry through increase reductiv...

Photoelectrodes enable simultaneous light absorption and catalysis of water splitting reactions. Their performance is established using electrochemical characterisation methods. Besides basic techniques such as voltammetry chronoamperometry, employed in the dark or under illumination, more advanced techniques, including (photo-)electrochemical impedance spectroscopy, intensity-modulated spectro...

The development of highly active and low-cost electrocatalysts with excellent durability is a major challenge for glucose catalysis. Here, we report fast electrodeposition method preparing new NiCuO flower-like nanostructure non-noble metals. catalyst shows significant efficiency electrooxidation, which reaches an oxidative peak mass activity 376.80 A g?1 retains 66% the original current over 1...

The graphene (GR) has attracted intensive interest due to its two-dimensional and unique physical properties. In the present study, the graphene sheets were synthesized by electrochemical exfoliation of graphite in sulfuric acid solution. The polybithiophene-graphene (PbTh-GR) composite films deposited onto indium tin oxide substrate (ITO/PbTh-GR) have been prepared by the incorporation of ...

Nickel is an essential engineering material and electrodeposited Ni has been widely used in many fields to improve surface finishing, corrosion resistance and wear properties. The kinetics of electrochemical deposition of nickel from chloride baths in the presence and absence of saccharin on the copper substrate was investigated by applying cyclic voltammetry and chronoamperometry measureme...
