摘要
An analysis method for determining trace arsemc and bismuth in iron, steel and alloysby hydride generation-atomic fluorescence spectrometry (HG-AFS) is presented. The operation parameters of AFS, effects of acidity, limit of coexisting ions and concentration of reducing agent have been tested. Thiosemicarbazide-ascorbic acid and phosphoric acid were used to eliminate the interference of matrix elements. The detection limits of arsenic and bismuth are 0.04 μg/g and 0.02 μg/g(3σ, n = 11), respectively. The method has been applied to determine trace arsenic and bismuth in middle and low alloy steel, ferronickel-base superalloy, nickel-base superalloy, cobalt-base superalloy and copper alloy with satisfactory results. The method was proved to be sensitive, accurate, quick and convenient.
