Abstract :A new rapid, reltable and accurate method for the spectrophotometric microdetermina- tion of Fe insert ignore into journalissuearticles values(III);, Co insert ignore into journalissuearticles values(II);, Ni insert ignore into journalissuearticles values(II); and Cu insert ignore into journalissuearticles values(II); using 2- insert ignore into journalissuearticles values(1- OH -3- SO3 H -7- naphythylazo); -chro- motropic acid insert ignore into journalissuearticles values(I);, is given. The optimum conditions favouring the formation of the complexes are extensively investigated. The molecular structure of ıhe complexes and their obedience to Beer’s law, as well as, their stabilities are also studied. A spectrophotometric titration method for Fe insert ignore into journalissuearticles values(III);, Co insert ignore into journalissuearticles values(II); and Ni insert ignore into journalissuearticles values(II); with EDTA using the named reagent as indicator is also given.
