A comparative study of vitamin B6 group and related compounds in buffered solutions using electrochemical techniques has been performed at neutral pH. Irreversible bi-or tetraelectronic processes are observed for these substances, and the electron transfer coefficient (αn) calculated. It was concluded that either the first or second electron transfer were the rate determining step of the electrode process. The diffusion coefficient of these substances was calculated and the values given follow an inverse tendency to the molecular size. For aldehydes the values obtained were corrected of the hydration reaction.It is important to remark that catalytic waves were reported for the first time for these compounds. Using a model involving the nitrogen of the basic structure the kinetic constants were calculated for most of them.

“…The study on verapamil, tamsulosin, and other synthesized indole compounds was realized by CV at GC electrode as a function of pH in order to identify the responsible atom for the second oxidation process of 1u. Our results revealed a good agreement with the redox mechanism postulated for similar compounds such as 4-methoxyphenol, tamsulosin and verapamil suggested that tamsulosin can be determined electrochemically by oxidation of methoxybenzene groups 40,41,45,46 .…”

“…The characteristics of the calibration plots are summarized in Table 2. The detection limit and quantification limit of the procedures (Table 2) were calculated according to the 3 s/m and 10 s/m criterions, respectively, where s is the standard deviation of the peak currents (five runs) and m is the slope of related calibration graph [45][46][47] .…”

“…The slope of 63.54 mV per pH was close to the theoretic value 59 mV per pH, suggesting one electron and one proton transferred in the oxidation of diclofenac sodium. The oxidative reaction of diclofenac sodium is a one electron, one-proton transfer process resulting in the radical species [37,38].…”

In this study, the main purpose is to fabricate a sensitive and selective electrochemical sensor through the multiwalled carbon nanotube-graphite/Ag electrode (MWCNTs-G/Ag). The application of this sensor was developed for the determination of diclofenac sodium in pharmaceutical dosage form, urine and human plasma. MWCNTs-graphite mixture improved the electroactive surface area due to its porous structure and a remarkable increase in the peak currents was observed. It demonstrated a catalytic effect and speeded up the rate of redox process. Application of MWCNTs-G/Ag resulted in a sensitivity augmentation. It is found that a maximum current response for the sensor in the Britton-Robinson buffer solution can be obtained in pH 3. The prepared sensor showed good standard calibration curves during 3 consecutive days over the concentration range of 45-2000 ng/mL and RSD values ranging from 1.95-7.11%. The limit of quantitation and detection limit were 45 and 15 ng/mL, respectively.
