摘要:

The oxidative dimerization reaction of o-amino phenol with dissolved oxygen is catalyzed by the presence of an extremely small amount of copper(II) ion. In a. c. polarography, the oxidation product of o-amino phenol gives a very sensitive tensammetric wave in the pH range 5 to 9. This tensammetric wave is used for the determination of copper(II) ion from 0.3 to 3.5 μg/100 ml final solution.
