Abstract
The anodic oxidation and cathodic reduction of coenzyme Qo (CoQ0) were studied using cyclic voltammetry (CV) at graphite electrode (C) in Britton -Robinson buffer (B.R.B) of pH ( 2-9). The result shows that the charge transfer processes were reversible over all pH range. The method is used to determine CoQ0 in concentration range ( 8.7 ×10-5 – 1.9 × 10-6 ) M at pH = 2 with a reduction potential of – 0.325 V and – 0.235 V for reduction and oxidation processes versus Ag / AgCl sat.
