The electrochemical behavior of VOQ(2)OH or [VOQ(2)-O-VOQ(2)] (Q = 8-hydrox
yquinolinate anion) has been investigated by cyclic voltammetry in acetonit
rile solutions. Although both species exist simultaneously at every conditi
on analyzed, they can be clearly differentiated by this method. The effect
of trace amounts of water on the electrochemical behavior is also discussed
.
