Electrochemical behavior and voltammetric determination of 4-aminophenol based on graphene–chitosan composite film modified glassy carbon electrode

Thermodynamic study of the electrochemical oxidation of some aminophenol derivatives: Experimental and theoretical investigation

“…Electrochemical oxidation of aminophenols at various conditions was studied by numerous workers [11][12][13][14][15]. Also electrochemical oxidation of aminophenols in the presence of different nucleophiles indicates that final products were produced via various mechanisms such as EC, ECE, ECEC, ECECCE and ECECEC [16][17][18][19][20].…”

Glass carbon electrode modified with horseradish peroxidase immobilized on partially reduced graphene oxide for detecting phenolic compounds

“…S3a, there were two reduction peaks at À0.35 V and À0.02 V in negative scan direction, corresponding to the reduction peak of direct electron transfer between HRP and electrode, and benzoquinone, respectively. For phenol, there were also two reduction peaks À0.25 V and 0.25 V in negative scan direction, corresponding to the reduction peaks of HRP catalytic intermediate II [33,34] and o-quinone, as shown in Fig. S3b.…”

“…Inset in Fig. 3b shows a linear relationship between the cathodic peak current and square root of scan rate, the high correlation coefficient illustrates that the redox reaction of immobilized HRP on the HRP/CRG24H/GC electrode should be a diffusion controlled process [25]. Fig.…”

Electrochemical determination of nonylphenol based on ionic liquid-functionalized graphene nanosheet modified glassy carbon electrode and its interaction with DNA

“…Chlorpromazine was successfully determined by using graphene paste electrode with low detection limit [27]. In addition, we also determined 4-aminophenol [28], catechol, resorcinol, and hydroquinone [29] with graphene-chitosan composite film modified glassy carbon electrode.…”
