| Abstract: | This research concerns the analysis of the metal ion binding of benzo‐ and pyridine‐azacrown ether compounds of different structures and sizes by potentiometric method. The ligands are able to form 1 : 1 complexes with heavy metal ions (Cu+2, Pb+2, Cd+2, Ag+, Ni+2, Zn+2) in water of middle or high stability. To understand the selectivity in cation binding, different factors were considered. |
