Abstract

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.
