Voltammetric Recognition of Ca~(2+) by Calix[4]arene Diquinone Diacid

摘要

The voltammetric study on a water-soluble calix[4]arene-diqumone-diacid (CDA) in pH 7.4 in the presence of Ca~(2+) ion provided important information about the unique electrochemical behavior of CD A-Ca~(2+) complex. Using CD A, Ca~(2+) ion in aqueous solution was recognized quantitatively by voltammetric techniques.
