MacroacyclicSchiff-base complexes based on transition metals and multidentate ligands are an interesting chemical field and have been the subject of extensive research due to their potential applications in fields of magnetochemistry, material science, catalysis, separation and ncapsulation processes, hydrometallurgy, formation of compounds with unusual properties and metalmetal interactions [8-25].

Chelation between [Cr.sup.3+] and HA was studied using FTIR spectroscopy to identify the functional groups involved in complex formation, possible multidentate character of the ligands, and the effects of pH as well as addition of increasing amounts of Cr(III) on the IR bands associated with carbonyl symmetric and asymmetric stretching.

Since it is reduced at more positive potentials and has no multidentate ligands which cause resistance against reduction process, it is much easier to reduce and it has a higher Cd (II) content in the final coverage.
In addition, the "multidentate" interaction between the many capture probes on the solid surface and the multiple CEs bound to 1 target leads to stronger capture than any single-capture probe-CE interaction alone.
Also, because of the multidentate nature of humic substances, it can be expected that the folding of the macromolecules (much like proteins) can bring various functional groups into the proximity of each other and, thereby, create binding sites that may significantly change the mechanism and strength of the metal cation speciation to humic substances.
