isoniazid (inh) was studied with regard to its electrochemical treatment on a strongly alkaline solution of a poly (3,4-ethylenedioxythiophene)-modified gold electrode, using both cyclic voltammetry and controlled potential techniques. this composite electrode exhibited 4-fold higher oxidation of inh, in accordance with peak densities, than the bare gold electrode. it was used the central compo...

Recent clinical and pre-clinical data demonstrate that adjuvant antimicrobial therapy is beneficial in cancer treatment. For the first time, an electrochemical method was proposed for the simultaneous determination of acyclovir (ACV) and methotrexate (MTX) at activated or electropretreated pencil graphite electrode (EPPEG). Their simultaneous determination was achieved by cyclic voltammetry (CV...

A microfluidic device designed for electrochemical studies on a microliter scale has been utilized for the examination of impurity levels in ionic liquids (ILs). Halide impurities are common following IL synthesis, and this study demonstrates the ability to quantify low concentrations of halide in a range of ILs to levels of approximately 5 ppm, even in ILs not currently measurable using other ...

A graphene-based carbon ionic liquid electrode modified with gold nanoparticles was fabricated. The electrochemical response of the modified electrode toward celecoxib was studied by means of cyclic voltammetry and differential pulse voltammetry. The structural morphology of the modified electrode was characterized by a scanning electron microscopy technique and electrochemical impedance spectr...

In this paper, we design and implement a portable potentiostat by using dual-microprocessors for the signal processing of electrochemical biosensors. In our design approach, one of the microprocessors is used to design the programmable waveform generator, and the other microprocessor is used to measure the current of biosensors. The proposed potentiostat can perform general electrochemical anal...

Cyclic voltammetry was used to explore the adsorption behavior of secnidazole on a hanging mercury drop electrode (HMDE). The effects of various operational parameters on the accumulation behavior of the adsorbed species were tested. Thus, a sensitive stripping voltammetry procedure for the determination of secnidazole with an adsorptive accumulation on the surface of HMDE has been developed. M...

The analytical in vivo chromium ion was searched for using a voltammetric hollow-fiber dialysis sensor via square wave stripping voltammetry (SW) , cyclic voltammetry (CV) , and chronoamperometry. Under optimum parameters, the analytical results indicated linear working ranges of 50~400 mg/l CV and 10~80 μg/l SW within a 30-sec accumulation time. The analytical detection limit (S/N) was 6.0 μg/...
