POTENTIOMETRIC, CONDUCTOMETRIC AND SPECTROPHOTOMETRIC STUDIES OF SOMEMETAL-ION COMPLEXES WITH REACTIVE DYES

The potentiometric, conductometric and IR spectra have been used to st udy the complexation of Cr(III), Ni(II), Pd(II), Pt(II), Zr(IV), UO22, La(III), Ce(III), Sm(III), Th(IV) and Os(VIII) with reactive dyes. T he stepwise and overall stability constants for complexes were determi ned potentiometrically. The ratio of the metal: ligand was determined conductometrically. On the other hand, the IR spectra are used to stud y the structure of metal-ligand complexes.
