    • Abstract


      The solid compounds of Y(III), La(III) and Ce(III) with 1-phenylazo-2-naphthol-3, 6-disulphonic acid (disodium salt) and itsp-nitroderivative were synthesized. The nature, composition and structure of the isolated solids have been elucidated by elemental analysis, conductometric titrations, UV-Vis and IR. It may be assumed that in both reagents the bond is only due to the sulphonic groups.
