Book Synopsis The Spectrophotometric Determination of Cobalt with 2-nitroso-1-naphthol. Laboratory Method No 27-5 by :
Book excerpt: Samples are taken into solution by a suitable procedure and are neutralized with sodium hydroxide. The solution is buffered, the iron oxidized, and the cobalt 2-nitroso-1-naphthol complex is developed and extracted into toluene. The organic phase is washed to remove impurities and the percentage transmittance of the solution is measured on a spectrophotometer.
