Decolourization of Anthraquinone Reactive Dye by Electrochemical Reduction on Reticulated Glassy Carbon Electrode
A remoção do corante reativo Reactive Blue 4 (RB4) por redução eletroquímica em solução aquosa foi investigada sobre eletrodo de carbono vítreo reticulado. O grupo antraquinona presente no corante RB4 é reduzido em pH < 8,0 em uma única etapa a hidroquinona, segundo um processo reversível de dois elétrons e reação de pré-protonação, via geração de um radical semiquinona detectado espectrotométr...
متن کاملElectrochemical reduction mechanism of camptothecin at glassy carbon electrode.
Camptothecin (CPT) is a cytotoxic quinoline alkaloid endowed with the inhibition of topoisomerase I, an essential enzyme for the normal functioning of DNA. The redox behaviour of CPT was investigated at a glassy carbon electrode using cyclic, differential pulse and square wave voltammetry. It was shown that CPT can undergo reduction in a pH-dependent mechanism. In acid media only one irreversib...
متن کاملSulfadiazine Determination in Pharmaceuticals by Electrochemical Reduction on a Glassy Carbon Electrode
Sulfadiazina foi quantificada em duas amostras de produtos farmacêuticos usando voltametria de onda quadrada. O sinal analítico foi obtido por redução em vez de oxidação da sulfa sobre eletrodo de carbono vítreo. A determinação eletroanalítica foi realizada em solução-tampão Britton-Robinson 0,04 mol L com pH 6,8. A redução irreversível da sulfadiazina foi observada em –1,49 V vs. Ag/AgCl. A cu...
متن کاملElectrochemical behaviour of dimethyl-2-oxoglutarate on glassy carbon electrode.
The electrochemical behaviour of dimethyl-2-oxoglutarate (MOG), a key intermediate in the Krebs cycle and an important nitrogen transporter in the metabolic pathways in biological processes, was investigated by cyclic voltammetry, square wave voltammetry and differential pulse voltammetry using a glassy carbon electrode. The reduction of MOG is an irreversible diffusion-controlled process that ...
متن کاملElectrochemical behavior and determination of clozapine on a glassy carbon electrode modified by electrochemical oxidation.
The adsorptive and electrochemical behaviors of clozapine (CLZ) were investigated on a glassy carbon electrode that was electrochemically treated by anodic oxidation at +1.8 V, following potential cycling in the potential range from -0.8 to 1.0 V vs. Ag/AgCl reference electrode. Based on the obtained electrochemical results, an electrochemical-chemical (EC) mechanism was proposed to explain the...
