The procedure involved the measurement of change in the electrophoretic mobility of the ligands upon increasing the metal ion concentration in the carrier electrolyte solution. A substantial increase in apparent electrophoretic mobility was observed for the crown ethers with increasing concentrations of the metal ions. The variations in increased electrophoretic mobility were attributed to the different stability of the complexes formed between the cations and the crown ether. The complex formation constants obtained with alkali metal cations were in the orders of: K+ &gt; Na+ &gt; Rb+ &gt; Cs+ (B18C6), K+ &gt; Na+ &gt; Rb+ &gt; Cs+ (DB18C6), Rb+ &gt; Cs+ &gt; K+ (DB21C7), and Rb+ &gt; Cs+ (DB24C8); while with alkaline earth metal cations it was: Ba2+ &gt; Sr2+ &gt; Ca2+ (B18C6) and Ba2+ &gt; Sr2+ (DB18C6). All the ligands examined showed no change in their apparent electrophoretic mobility upon changing Li+ and Mg2+ concentrations, indicating less reactivity with the cations. From the results obtained in this study, the electrophoretic method was proved to be preferable for analyzing the reactivity of the crown ethers and the selectivity toward metal cations.</jats:p>"}]}],"creator":[{"@id":"https://cir.nii.ac.jp/crid/1380017671278672384","@type":"Researcher","foaf:name":[{"@value":"Ludovick C
