| Abstract: | Various test conditions and effect factors for determing trace vanadium in steels and alloy steels by graphite furnace AAS were discussed. The improved signal shapes, in- creased sensitivity and eliminated memory effects were obtained with the use of pyrolytic graphite tube combined with optical temperature control accessory and within the range of stable atomization temperature. The established method was applied to the determination of trace vanadium in steels and alloy steels with satisfactory results. |
