The aim of this paper is to study the high order difference scheme for the solution of a fractional partial differential equation (PDE) in the electroanalytical chemistry. The space fractional derivative is described in the Riemann-Liouville sense. In the proposed scheme we discretize the space derivative with a fourth-order compact scheme and use the Grunwald- Letnikov discretization of the Ri...

Various carbon-based sensors (graphene, carbon nanotubes, graphite, pencil glassy carbon, etc.) have distinctive behavior and a broad range of importance for identifying sex hormones like estriol, estradiol, estrone, progesterone, testosterone. The current review emphasizes voltammetric, amperometric, electrochemical impedance spectroscopic methods detecting some these hormones. existence, stru...

Introduction: Omeprazole is one of the most used proton-blocking molecules applied in gastric ulcer treatment. Its blocking effect achieved by presence both acidic and basic nitrogen heteroatoms its composition. Nevertheless, due to collateral effects, which may be moderate severe, development electrochemical determination really actual. Methods: In this work, we describe theoretically possibil...

The particular analytical performance of ultramicroelectrode arrays (UMEAs) has attracted a high interest by the research community and has led to the development of a variety of electroanalytical applications. UMEA-based approaches have demonstrated to be powerful, simple, rapid and cost-effective analytical tools for environmental analysis compared to available conventional electrodes and sta...

A sensitive electroanalytical method for determination of acetaminophen (ACT) in paracetamol tablet has been developed and validated. Cyclic voltammetry (CV) was used to study the electrochemical behaviour of paracetamol, while differential pulse voltammetry (DPV) was used to determine ACT. Screen printed carbon electrode was used for the analysis. Determination of all parameters in paracetamol...
