摘　　要：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。A highly sensitive chromogenic reaction of vanadium with o-chlorophenylfluorone and cetyltrimethylammonium bromide has been investigated.The molar absorptivity is 1.1×10~5 L· mol^(-1)·cm^(-1). Interference of iron can be eliminated by extraction with MIBK. The method has been applied to determine microamounts of vanadium in steels.
