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