Two new sporopollenin-immobilized Schiff bases,S-[N-(2-aminoetil) salicylaldiimino] and S-[N-(2-aminoetil) benzaldiimino],and their cobalt(III) and nickel(II) complexes,S-[N-(2-aminoetil) benzaldiimino] aquatriacetato cobalt(III),S-[N-(2-aminoetil) salicylaldiimino] aquadiacetato cobalt(III),S-[N-(2-aminoetil) benzaldiimino] diacetato nickel(II),and S-[N-(2-aminoetil) salicylaldiimino] diacetato nickel(II),were synthesized onto a chemically modified sporopollenin with ethylenediamine.The immobilized ligands and their metal complexes were characterized by thermal analysis and spectroscopic techniques such as infrared,ultraviolet-visible,and atomic absorption spectrometry.Immobilized Schiff base metal complexes,S-[N-(2-aminoetil) benzaldiimino] aquatriacetato cobalt(III) and S-[N-(2-aminoetil) salicylaldiimino] aquadiacetato cobalt(III),were used as ligand exchanger media to investigate ligand adsorption behavior of methylene blue(MB) with column technique.The result shows that the chelation of methylene blue with S-[N-(2-aminoetil) salicylaldiimino] aquadiacetato cobalt(III) complex increases ligand adsorption capacity.

Immobilized Schiff base metal complexes, S- (N- (2-aminoetil) benzaldiimino] aquatriacetato cobalt (III) and S- [N- (2- aminoetil) salicylaldiimino] were used as ligand exchanger media to investigate ligand adsorption behavior of methylene blue (MB) with column technique.
