Among other organic reagents, a group of nitroso compounds, related to nitroso-naphthols, is highly selective for cobalt, such as 2-nitroso-5-dimethylaminophenol (1,2-dichloroethane, e = 6.2-10" ) [54,55], and 3-nitroso-2,6-pyridinediol (e = 3.4-10 ) [56]. 

Various organic reagents have found application in the determination of vanadium, namely Pyrogallol Red in the presence of surfactant [67], Bromopyrogallol Red (e = 7-10 at 580 nm) [68], Alizarin S (in the presence of CP) [69], formaldoxime [70], 2-nitroso-5-dimethylaminophenol [71], 2,2 -dipyridyl-2-quinolylhydrazone [72], pyrogallol [73-75], and carminic acid in the presence of surfactant [76].
