摘要:

A highly selective and sensitive method is described for the determination of para- as well as ortho-isomers of aminophenol. The method involves oxidative coupling of aminophenol with Berthelot hypochlorite-alkaline phenol reagents. The reaction yielded a blue chromophose with p-aminophenol (∑=10,000 at 633 nm) and a dark green chromophore with o-aminophenol (∑=1436 at 845 nm). The reaction mechanisms involved in the chromophore formation are discussed.
