本文研究了钒与OCIPF和CTAB的显色反应,其摩尔吸光系数为1.10×10~5,是已见报道的测钒的荧光酮类显色剂中灵敏度最高的体系。采用甲基异丁基酮从含钒溶液中萃取分离铁,使该体系能够应用于水相中测定某些钢铁中的微量钒。
In this paper, the color reaction of vanadium with OCIPF and CTAB has been studied. The molar absorption coefficient of vanadium is 1.10 × 10 ~ 5. It is the most sensitive system of fluorogenic ketones reagent reported. The use of methyl isobutyl ketone to extract and separate iron from the vanadium-bearing solution enables the system to be used in the determination of trace amounts of vanadium in some steel in the aqueous phase.
