摘　　要：探讨了石墨炉原子吸收法测定钢铁及合金中微量钒的各种实验条件及影响因素。 实验表明，采用热解涂层管与光控升温相结合并在温度稳定的情况下原子化，可改善信号峰 形，提高灵敏度，消除记忆效应。方法用于钢铁及合金中钒的分析，结果令人满意。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.
