Özet:

 

A novel azo derivative, 2,3,4,6'-tetrahydroxy-3'-sulfoazobenzene  (THSA), was synthesized by using pyrogallol.  The acid dissociation  constants, or Ka values, of THSA were determined by the UV-visible  spectroscopic technique.  The protonation and deprotonation behaviors  of the title molecule were studied from the super basic to the super  acid region (i.e. 10 N NaOH to 98% H2SO4), including the pH region.  A selective and sensitive UV-visible spectrophotometric method was  devised for determination of aluminum by using this ligand.  The  developed method was successfully applied to an alunite mineral and to  pharmaceutical preparations for the determination of aluminum.
