Abstract EN
The present work includes a detailed investigation of a new spectrophotometric method for the determination of 1-naphthylamine.
The method is based on oxidative coupling reaction of the compound with catechol in the presence of potassium chromate as oxidant in acidic medium to form a stable purple–red coloured product which shows maximum absorption at 530 nm.
The molar absorptivity is 3685 l.mol-1.cm-1.
Beer's law is obeyed over the range of (1- 60) ppm.
The method is applied to the recovery of 1- naphthylamine from sea and river water.
