“…Recently, the preparation of a PCV-modified glassy carbon electrode and its use in the electrocatalysis of ascorbic acid and dopamine oxidation was reported by Cai and Xue [33]. Later, Golabi et al reported the PCV-modified electrode by electrochemically deposition on the surface of glassy carbon electrode and were used for the detection of hydrazine [34] and NADH [35]. However, some of those dyes modified electrodes need activated previously and time-consuming.…”

“…In electrochemistry, it has been demonstrated that chemically modified electrodes possess distinct advantages over conventional electrodes in numerous application areas including electrocatalysis and electrochemical sensors. [1][2][3][4][5][6][7] One of the important properties of the chemical modified electrodes (CMEs), which has been the subject of considerable study, is their ability to catalyze the oxidation and reduction of solute species which exhibit high overpotential at unmodified electrode surfaces. The CMEs offer a possibility of lowering the overpotential and increasing sensitivity and selectivity of some electroactives species.…”

) 2 = 0,85 V apresentou uma resposta eletrocatalítica para os compostos sulfidrílicos; L-cisteína e N-acetylcisteína. A oxidação eletrocatalítica dos compostos sulfidrílicos pelo mediador foi empregada para a determinação de L-cisteína e N-acetilcisteína. O eletrodo de pasta de grafite modificado para a determinação de L-cisteína e N-acetilcisteína apresenta uma linearidade de 9,2 × 10 -4 -2,0 × 10 -2 e 9,6 × 10 -4 -1,4 × 10 -2 mol L -1 com limite de detecção de 1,9 × 10 -4 mol L -1 e 1,5 × 10 -4 mol L -1 e desvio padrão relativo de ± 5 e 4% (n=3) ) 2 = 0.85 V presents an electrocatalytic response for sulfhydryl compounds. The electrocatalytic oxidation of sulfhydryl compounds by the mediator has been used for the determination of L-cysteine and N-acetylcysteine. The modified graphite paste electrode gives a linear range from 9.2 × 10 -4 -2.0 × 10 -2 ; 9.6 × 10 -4 -1.4 × 10 -2 mol L -1 for the determination of L-cysteine and N-acetylcysteine, respectively, with detection limit of 1.9 × 10 -4 mol L -1 ; 1.5 × 10 -4 mol L -1 and relative standard desviations ± 5% and 1.5 × 10 -3 mol L -1 ± 4% (n=3). The amperometric sensitivities are 0.024 and 0.027 µA/µmol L -1 for L-cysteine and N-acetylcysteine, respectively. The application of this electrode was tested and a commercial pharmaceutical product (Fluimucil) has been determined.

“…In continuation of our studies concerning the preparation of modified electrodes [20][21][22][23][24][25], in the present work, we found that a tetrabromo-p-benzoquinone modified carbon paste electrode (TBQ-MCPE) possesses high stability and good electrocatalytic activity toward the electrocatalytic oxidation of AA. Cyclic voltammetry was used to characterize the electrochemical properties of the TBQ-MCPE and to investigate its electrocatalytic effect on AA oxidation.…”
