A comprehensive scheme for the analysis of a wide range of steels by atomic-absorption spectrophotometry

摘要: The determination of manganese, nickel, chromium, molybdenum, copper, vanadium, cobalt, titanium, tin, aluminium and lead in steel by a direct atomic-absorption method, which involves single dissolution based on perchloric acid, is described. scheme effects considerable savings time compared with traditional methods, comparable accuracy.The serious depressive interferences caused iron the response some elements are overcome nitrous oxide-acetylene flame, minor corrected for inclusion calibration standards. No other inter-elemental were encountered acid solutions presence iron.Silicon tungsten, not retained solution this scheme, determined after separate sample.Results obtained British Chemical Standard steels tabulated, accuracies discussed.
