Cyclic voltammetric technique using glassy carbon electrode of cobalt chloride Co(II) was studied in blood medium for the effect of ascorbic acid as an electrocatalyst reagent on the oxidation reduction current peaks of Co(II). It was found that the two oxidation reduction current peaks for Co(II) in 0.1M KCl as electrolyte were at 900 and 250 mV respectively. In the study of Co(II) in blood medium the result was different, in that the reduction current peak disappeared and the oxidation current peak shifted to a higher potential at 1.4 V. The other study for the effects of different concentrations of ascorbic acid on the anodic current peak of Co(II) in blood medium showed an enhancement of the oxidation current peak about three times and the ascorbic acid acted as an electrocatalyst in blood components which caused damage to blood cells.

“…Electronic spectral properties also showed that the sulphur donor atom of L1 weakened the ligand field with respect to ligand-to-metal charge-transfer band. [13][14][15][16][17].…”

“…Cyclic voltammetric technique was used by scientists to identify the impact of chemical compounds on the blood components during the exposure of the body to pollutants or drugs [1][2][3][4][5][6]. Recent studies have confirmed that antibiotic compounds after being converted to nanoparticles showed great effect on the elimination of different types of bacteria which cause diseases [7].…”

For the first time, one of the antibiotic nanoparticles such as a classical form of ampicillin trihydrate compound was studied. The electrochemical behavior of ampicillin nanoparticles was investigated in blood medium using cyclic voltammetric technique by glassy carbon electrode. The results showed that the oxidation-reduction current peaks of ampicillin nanoparticles in blood medium were different from that of microparticles. The nanoparticles acted as anti-oxidative antibiotic by making the oxidation current peak at 1 V disappear, while the oxidation peak of microparticles still appeared in blood medium; hence, ampicillin at microform acted as oxidative reagent in blood medium. A good reliability and stability of glassy carbon electrode in blood medium was found with low values of RSD for oxidation-reduction current peaks at ±0.52% and ±0.038% respectively. Scanning electron microscopy for the characterization of ampicillin trihydrate nanoparticles was studied.

“…Electrochemical studies by cyclic voltammetric method with modified working electrodes were realized for the redox current peaks of the pollutants in the blood medium [1][2][3][4][5][6][7]. Children polluted with higher levels of metals, such as lead and antimony in their urine suffered from more severe autism, suggesting that metal levels in their bodies may contribute to its seriousness [8][9][10].…”

Lead is considered a key element in causing autism disease in children due to the pollution of this dangerous element to human. The aim of this research is to obtain a chemical compound with the effect of inhibiting the oxidation of lead ions on the brain that causes the autism disease. Cyclic voltammetric technique was used to study the effect of interferences between lead ions with selected elements such as Mn(II), Mg(II), Zn(II), Ca(II), PO 4 -3 and Co(II) in blood medium. Multi wall carbon nano tube (MWCNT) which was modified with glassy carbon electrode (GCE) was used as a working electrode sensor in cyclic voltammetric method. The results showed that the oxidation and reduction current peaks of Pb(II) ions in the blood medium appeared at -0.2 and -0.8 V respectively. It was found that Co(II) ions had a significant effect on the Pb(II) ions in blood medium as anti-oxidative reagent by reducing the anodic current peak of Pb(II) with five folds and enhancing the cathodic current peak. But other ions such as Mn(II), Mg(II), Zn(II), Ca(II) and PO 4 -3 reduced both redox current peaks of Pb(II) in blood medium. It means that Co(II) ions acted as a good anti-oxidative reagent in blood medium which reduced the effect of lead ions on brain cells by the blood stream. Hence, cobalt compounds could be used as drugs for treatment of the autism disease in children.
