The sample, containing a slight excess of nitric acid, is treated with sodium citrate, acidified with acetic acid, and the cobalt complexed with potassium ethyl xanthate. The complex is extracted into chloroform, which is then removed by evaporation and after oxidation of any residual organic matter with nitric acid, the cobalt is dissolved in hydrochloric acid. Sodium, acetate solution and the nitroso-R salt reagent are added and the solution boiled with nitric acid to destroy any other metal complexes present. After boiling for an optimum time the solution is cooled, diluted to a known volume and its absorbency determined. (auth)
