    Sorption of Target Anions by Ligand Exchange
    (JOHN WILEY & SONS INC, 1998) Çengeloğlu, Y.; Mercimek, B.; Kara, H.; Ersöz, M.
    The sorption of anionic ligands such as I-, Br-, and SCN- onto diaminoethyl-sporopollenin (DAE-Sporopollenin) was investigated in both column and batch experiments at room temperature. The isotherm binding constants suggest that the resin is most efficient at the binding of I- compared with Br- or SCN-. The general ligand sorption affinity series observed was I- > Br- > SCN-. This ligand sorption could be described by considering the hydration of ions in the exchanger. The sorption behavior of the ligand exchanger and the possibilities of selectively removing and recovering ligands are discussed on the basis of their chemical and complexing properties.

    The Synthesis of Four New Schiff Bases and Some of Their Transition Metal Complexes
    (MARCEL DEKKER INC, 1998) Uçan, H. I.; Karataş, I.; Irez, G.; Deveci, M. A.; Mercimek, B.
    Isonitrosoacetophenone, synthesized by nitrosotion of acetophenone, has been condensed with diamines (1,4-phenylenediamine, 4,4'-diaminobiphenyl, 4,4'-diaminodiphenylmethane or 4,4'-diaminodiphenylether) to obtain the tetradentate Schiff bases 1,4-phenyliminobis(isonitrosoacetophenone), 1,1'-biphenyl-4,4'-diiminobis(isonitrosoacetophenone), 1,1'-diphenylmethane-4,4'-diiminobis(isonitrosoacetophenone) or 1,1'-diphenyloxy-4,4'-diiminobis(isonitrosoacetophenone). The polymeric Ni(II) and Cu(II) complexes of these Schiff bases are square-planar while the polymeric Co(II) complexes are octahedral with water molecules at the axial positions. The structures of the above complexes were determined by H-1 NMR and IR spectroscopy and elemental analyses.
