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。 The various experimental conditions and influencing factors for the determination of trace vanadium in steel and alloy by graphite furnace atomic absorption spectrometry were discussed. Experiments show that the combination of pyrolytic coating tube and light temperature control and atomization under stable temperature can improve the signal peak shape, increase the sensitivity and eliminate the memory effect. The method was applied to the analysis of vanadium in steel and alloy with satisfactory results.
