RISElectrochemical determination of riboflavin using a synthesized ethyl[(methythio)carbonothioyl] glycinate monolayer modified gold electrode
B2 (VB2) species were linear for VB2 concentrations in the range from 10–6 to 10–2 M. The effect of pH, type of buffer solution and scan rate on the response of the modified electrode was studied. The constructed electrochemical sensor responses very...
Development of a dimethyl disulfide electrochemical sensor based on electrodeposited reduced graphene oxide-chitosan modified glassy carbon electrode
oxide (GO) and the chitosan, and also the pH of the solution have been investigated and optimized. Analytical performance of the CS/RGO/GC modified electrode for determination of DMDS has been evaluated. Under optimized operating conditions, a...
Fabrication a new modified electrochemical sensor based on Au–Pd bimetallic nanoparticle decorated graphene for citalopram determination
electrodewith simple electrodeposition method. The morphology and the electrochemical properties of the modified electrode were characterized by scanning electron microscopy (SEM), transmission electron microscopy (TEM), atomic force microscopy (AFM), energy...
Development of a modified glassy carbon electrode electrochemical sensor based on electrodeposited graphene - chitosan film for determination of dimethyl disulfide (DMDS) in seawater
Dimethyl disulfide (DMDS) is a sulfur compounds with an unpleasant smell which is usually released from the oceans and seawaters and considered as an environmental problem for neighborhood areas. Therefore, it is of paramount ...
Electrochemical determination of carbamazepin in the presence of paracetamol using a carbon ionic liquid paste electrode modified with a three-dimensional graphene/MWCNT hybrid composite film
/MWCNT) hybrid composite. The modified electrode (GR/MWCNT/CILPE) was used for measurement of carbamazepine (CBZ) in the presence of paracetamol (PA) with an excellent electrochemical catalytic behavior. The application of the electrode was investigated by cyclic...
A new electrochemical sensing platform for quantitative determination of diclofenac based on gold nanoparticles decorated multiwalled carbon nanotubes/graphene oxide nanocomposite film
. The oxidation peak current of diclofenac was linear in the concentration ranges of 0.4–80
µM and 100–1000 µM with a detection limit of 0.09 μM. The modified electrode was used for the quantitative determination of diclofenac in water, tablet and human urine...
