Study the voltammetric behavior of 10-Hydroxycamptothecin and its sensitive determination at electrochemically reduced graphene oxide modified glassy carbon electrode
10-Hydroxycamptothecin; Electrochemically reduced graphene oxide; Determination; Electrochemical properties Abstract The electrochemical properties of 10-Hydroxycamptothecin were investigated systematically at a reduced graphene oxide modified glassy carbon electrode. A new pair of redox peaks of 10-Hydroxycamptothecin was reported for the first time with quasi-reversible process driven by adso...
متن کاملElectrocatalytic Determination of Isoniazid by a Glassy Carbon Electrode Modified with Poly (Eriochrome Black T)
In this work poly eriochrome black T (EBT) was electrochemically synthesized on the glassy carbon electrode as electrode modifier. On the modified electrode, voltammetric behavior of isoniazid (INH) was investigated. The poly (EBT)-modified glassy carbon electrode has excellent electrocatalytic ability for the electrooxidation of isoniazid. This fact was appeared as a reduced overpotential of I...
متن کاملElectrochemical Chiral Recognition of Naproxen Using L-Cysteine/Reduced Graphene Oxide Modified Glassy Carbon Electrode
The electrochemical response of S- and R-naproxen enantiomers was investigated on L-cysteine/reduced graphene oxide modified glassy carbon electrode (L-Cys/RGO/GCE). The production of the reduced graphene oxide and L-cysteine on the surface of the glassy carbon electrode was done by using electrochemical processes. Cyclic voltammetry (CV) and electrochemical impedance spectroscopy (EIS) were us...
متن کاملVoltammetric Determination of Chloramphenicol at Electrochemically Pretreated Glassy Carbon Electrode
A sensitive square wave voltammetric method for the determination of chloramphenicol (CAP) was developed using electrochemically pretreated glassy carbon electrode (EPGCE). Electrochemical pretreatment of the electrode greatly enhanced the reduction peak current (Ip) of CAP. The electrochemical investigation of CAP was carried out by using cyclic and square wave voltammetry techniques. CAP show...
متن کاملElectrochemical behavior and voltammetric determination of theophylline at a glassy carbon electrode modified with graphene/nafion.
An ultrasensitive voltammetric sensor, a simply coated graphene-Na?on suspension on a glass carbon electrode surface, was fabricated and used to investigate the electrochemical behavior of theophylline as described in the present paper. The results indicated that this voltammetric sensor exhibited a special recognition capacity to determine theophylline as well as having high sensitivity due to...
