SPECTROPHOTOMETRIC DETERMINATION OF RARE EARTH METALS WITH 1-(2-PYRIDYLAZO)- 2-NAPHTHOL
Journal Article
·
· Analytica Chimica Acta (Netherlands)
1-(2-Pyridylazo)-2-naphthol (PAN) reacts very sensitively with rare earth metals to form a deep red precipitate in alkaline solution; this can be extracted with ether, except in the case of lanthanum, cerium, and scandium. Absorption maxima occur at 530 and 560 m . Traces of rare earth metals may be determined in the presence of many foreign metals. (auth)
