Abstract
Complexation of Zn(II), Cd(II), Hg(II), Ti(IV), Zr(IV) and
Pd(II) with two anthraquinone derivatives, alizarin blue sky
( ABS) and disperse blue (DB), was studied
spectrophotometrically. The spectral behaviour of the ligands
were investigated. The suitable conditions for complexation
were selected and the stoichiometry of the complexes in
solution were determined. The solid complexes were isolated and
characterized by elemental analysis and IR data. The mode of
ligands binding were investigated. Analytical procedure for
quantitative determination of Ti(IV) in Ti02 using ABS as an
analytical reagent was developed.
