A new catalytic kinetic method with second derivative oscillopolarography detection for determining trace amounts of NO〓〓 has been developed. The method is based on the catalytic oxidation of Amarath by potassium bromide in the diluted H〓SO〓. The detection limit of the method is 2.8×10〓g/ml, the linear range of the determination 〓is 0.6～14ng/ml for NO〓.
