Abstract

Specifies a spectrophotometric method for the determination of cobalt content up to 12% in all grades of iron and steel containing less than 10.0% copper. The sample is dissolved in acid and nitroso-R-salt added. This forms a red-brown chromophore which is measured spectrophotometrically at 580 nm.
