Abstract Preparation of nano tantalum pentoxide and nano cobalt sulfate were prepared by ball milling using Retsch MM2000 apparatus with three stainless steel balls having diameter 12 mm.Preparation of new working electrode was done by adding nano tantalum petoxide to multicarbonnatubes and carbon with specific ratioand finish nano paste put at the tip of glassy carbon electrode and used for use.The redox reaction of nano cobalt sulfate were studied in 0.1M KBr alone at two temperatures 292.15K and 297.15 using cyclic voltammetry.Different solvation and kinetic parameters were calculated at the used two temperatures and their data were discussed.Interaction parameters of the nano cobalt sulfate with Fucgsin acid dye was done to study the complexationcharcheterbeteen the two cyclic voltammetrically and the resulted data are discussed.Different thermodynamic data were evaluated for the interaction of nanocobal sulfate NCS with Fuchsin Acid, FA like stability constants, Gibbs free energies of complexation, enthalpies and entropies were evaluated and their values were discussed

The Impact

The cyclic voltammetric electrochemical technique was utilized to investigate the effect of different temperatures on the redox current peaks of rifampicin (RF), a drug commonly used to treat many diseases including tuberculosis (TB), in vitro for human blood medium. A modified working electrode of glassy carbon electrode (GCE) with carbon nanotube (CNT) (CNT / GCE) was used as a sensitive nano-sensor to evaluate the impact of temperature on the blood medium in the presence of RF ions. The results confirmed the presence of two oxidation and one reduction current peaks of RF in blood medium at 0.5, 1, and -0.5 V respectively. The redox current peaks of RF ions in blood medium were enhanced with increasing the temperature from 20 to 36oC. The activation energy (E*) values were determined by applying Arrhenius equation with oxidative and anti-oxidative peaks of Ea*(Ipa)= 9.252 and 11.026 kJ.mol-1.K-1,respectively. Other thermodynamic functions such as the change in each of activation Enthalpy (ΔH*), activation Gibbs energy (ΔG*) and activation Entropy (ΔS*) values were estimated using Eyring equation. The present results of the effects of different temperatures on the blood status in presence of RF lead to the explanation of the oxidative stress of the drug which used in an inflammatory of blood at different temperature.
