Abstract:	The differential pulse polarographic determination of the vanadium (V) ion coupled with a catalytic homogeneous reaction was carried out in a system containing the vanadium (V)-PAR complex and an oxidant in acetic/acetate buffer. On addition of the powerful oxidant, sodium bromate, the peak current for the reduction of the vanadium (V) complex was increased significantly by about 21 times. A calibration plot was found to be linear in the concentration range 0.05-0.25 μg/ml and the detection limit was 5 ng/ml. © 1991 Springer-Verlag.
