The electrochemical effect of different temperatures on sodium saccharine in blood medium using modified working electrode CNT/GCE by cyclic voltammetry

Sodium Saccharin (NaSc) was studied as a chemical compound used for diabetic patients as a replacement for natural sugar. The study was focused on the effect of different temperatures on NaSc in human blood medium using cyclic voltammetric technique at modified glassy carbon electrode (GCE) with carbon nanotubes (CNT) as working electrode (CNT / GCE). The physical chemistry functions were studied for the activated values in terms of enthalpy (Delta H*), free energy (Delta G*) and entropy (Delta S*) for redox current peaks of NaSc in blood medium at both electrodes, GCE and CNT / GCE using Eyring equations. Also, the study included the determination of the activation energy (Ea*) determined by Arrhenius equations for the redox current peaks of NaSc to compare values obtained by GCE and CNT / GCE. It was found that the values of thermodynamic functions were different due to the oxidation - reduction reaction of NaSc in blood medium which reacts with many complex compound with the component of the blood especially hemoglobin as ferric and ferrous ions. The oxidative stress of NaSc in blood medium appeared clearly in voltammogram.
