矿石及铁矿石中钒的原子吸收测定已有资料报道.它们用铝盐作干扰抑制剂,克服了一些元素对钒的干扰,但没有研究在大量钛存在下对钒的影响.本文以钒钛磁铁矿为试样,进一步对钛等主要组分和有关条件进行了试验,发现仅用铝盐抑制钛的干扰效果不好,当有高氯酸共存时,效果明显增加,可不分离钛直接测定钒.因钛精矿和钒钛高炉渣试样难于用酸分介完全,故用碱熔法,带入的大量钠离子显著增强钒的吸收信号,但加入铝盐和扣除钠的分子吸收后
Atomic absorption measurements of vanadium in ores and iron ores have been reported. They use aluminum salts as interference inhibitors to overcome some of the elements of vanadium interference, but did not study the presence of a large amount of titanium vanadium.In this paper, vanadium Titanomagnetite as a sample to further test the main components such as titanium and related conditions and found that only the use of aluminum salts inhibit the interference of titanium is not good, when the coexistence of perchloric acid, the effect was significantly increased, without separation of titanium Direct determination of vanadium due to titanium concentrate and vanadium-titanium blast furnace slag sample is difficult to completely separate the acid, so the alkali melting method, brought a large number of sodium ions significantly enhance the absorption of vanadium signal, but adding aluminum salt and sodium molecules After absorption
