1 Ethylenediamine tetra Methylenephosphonic acid is a new multidentate ligand.

2 The development of the multidentate complexes applied in the atomic absorption spectrometry has been reviewed.

3 Complex formation with multidentate ligands is called chelation, and the complexes are called chelates .

4 What's more prominent is that MAT can are very important terminal blocks in the synthesis of multidentate organosuifur compounds which can self-assemble on gold surface.

5 In this review the application prospect of the solvent extraction and floatation of multidentate complexes, surfactants and multicomponent heteropoly acids in AAS were also included.

6 This review covers the developments in the field of instrumental analysis of multidentate complexs in the 1990′s.

7 The synthesis, IR spectrum properties, crystal structure and quantum chemistry of multidentate ligand tris(2benzimidazylmethyl)amine (NTBH2O) are reported in this paper.
