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.
