Determination of cobalt and zinc in nickel metal by atomic-absorption spectrophotometry after separation by simultaneous chloroform extraction of their thiocyanate-diantiprylmethane complexes: M34-20/93E-PDF

“An atomic-absorption spectrophotometric method for determining cobalt and zinc in the range 0.0005 to 0.10% in nickel metal is described. After sample dissolution, cobalt and zinc are separated from the matrix element by simultaneous chloroform extraction of their thiocyanate-diantipyrylmethane ion-association complexes from a citric acid medium at pH 3.25. Interference from copper and various elements (i.e. titanium, vanadium, molybdenum, tungsten, etc.) is eliminated with thiourea and ammonium fluoride, respectively. Cadmium, iron and chromium also interfere under the chosen experimental conditions, but the amounts of these impurities present in nickel metal are so low that their interference effects are negligible. Other impurities do not interfere in the proposed method"--Abstract, p. i.
