;1996, 7(3): 275-278.
-
Three new azo-reagents having different numbers of hydroxy groups ortho to the azo-group,i.e., 2-(2',4',6'-trihydroxyphenylazo)-, 2-(2',4'-dihydroxyphenylazo)-and 2-(4'-hydroxyphenylazo)benzenearsonic acid,were synthesized.Through comparative studies on the reactions of the three reagents with various metal ions,especially with iron(Ⅲ),it was found that not only selectivities but also sensitivities of azo-reagents can be improved by utilizing rationally the steric effect of groups ortho to the azo-group.The reasons for the improvements were discussed.
