STUDIES ON SCHIFF BASE COMPLEXES Ⅶ.COORDINATION EFFECT OF SCHIFF BASE SUPPORTED ON SILICA
Abstract:
Several Schiff base supported silicas have been prepared and their adsorption capacities for metal ions were measured. compared to the Schiff-base-free silica the adsorption capacity of the functionalized ones were greatly improved in the order:Cu2+ > Co2+ > Cd2+ > Pb2+.The Nls photoelectron spectrum of Cu2+ complex with surface Schiff base was quite different from that of Cu2+ ion-free surface Schiff base. Owing to the more extensive back-bonding in the metal-coordinated-N=C-group, the Nls binding energy is far lower for the coordinated group than for the free one.
