In this present study, ionic liquid (1-butyl-3-methylimidazolium hexafluorophosphate (IL)) modified pencil graphite electrode (IL-PGEs) was developed for electrochemical monitoring of DNA hybridization related to Microcystis spp. (MYC). The characterization of IL-PGEs was performed using microscopic and electrochemical techniques. DNA hybridization related to MYC was then explored at the surfac...

In this paper, pretreated pencil graphite electrode (Pre-PGE) was used for the determination of insulin by anodic stripping differential pulse voltammetry (DPASV). The influences of the pretreatment procedures, pH values, accumulation potential and time on the signal enhancement of insulin were optimized, and a novel electrochemical method for the determination of insulin was described. The cur...

Parkinson's disease (PD) is a degenerative disorder of the central nervous system. The motor symptoms PD result from death dopamine-generating cells in region mid brain and dopamine precursor levodopa (L-Dopa) used for treatment. Carbidopa (Car) administered association with L-Dopa pharmaceutical formulation as an inhibitor on decarboxylase activity. Thus, their simultaneous determination great...

A Pd-encapsulated graphite electrode was used as the negative electrode in Li-ion cells. Through dispersion of ultrafine nanoparticles of palladium on the surface of graphite, the interfacial properties of the carbon surface were modified. The presence of the palladium Ž . dramatically reduces the initial irreversible capacity of the graphite in propylene carbonate PC -based electrolyte. Pallad...

A new simple, cheap, and rapid method to increase the sensitivity of pencil graphite electrode (PGE) determine Linagliptin (LNG) was developed by modified PGE with copper microparticles (Cu-PGE). The disposable sensor electrode's preparation depended on electrodeposition Cu-microparticles that can be applied for determined LNG complexed it Cu+2 ions measure LNG-Cu complex onto Cu-PGE improved. ...

The work demonstrates the development of an electrochemical sensor for quantification Chloramphenicol (CA) using pencil graphite electrode (PGE) modified with Gadolinium tungstate nano flakes and carbon fibers composite (PGE/GWNfs/CNFs). was further characterized confirmed by X-ray diffraction (XRD), energy-dispersive spectroscopy, transmission electron microscopy analysis. prepared GWNfs/CNFs ...

background: high concentration of salt makes biological treatment impossible due to bacterial plasmolysis. the present research studies the process of electrochemical oxidation efficiency and optimal levels as important factors affecting ph, salt concentration, reaction time and applied voltage. methods: the sample included graphite electrodes with specifications of 2.5 cm diameter and 15 cm he...
