 The cyclic voltimetric technique using a glassy carbon electrode was studied for the effect of ascorbic acid on the oxidation reduction current peaks of cobalt chloride Co2 in blood medium, and it was found that the reduction current peak disappeared and the oxidation current peak shifted to a higher potential at 1.4V, while the anodic current peak of Co2 was enhanced about three times due to ascorbic acid acting as an electrocatalyst in blood components which caused damage to blood cells.
