Electrochemical investigation of anthraquinone-based chemodosimeter for Cu2+ metal ion

Abstract

The electrochemical properties of an anthraquinone-containing Cu 2+-promoted desulfurization chemodosimeter (AQCD) in the presence of various metal ions were investigated by voltammetry. AQCD showed voltammetric changes toward divalent metal ions (M2+), which are similar to those of anthraquinone (AQ) and 1-aminoanthraquinone (AQNH2) with the metal ions except Cu2+. This can be explained on the electrostatic interaction (AQCD-M2+) and chemodosimetric reaction (AQCD-Cu 2+). © 2013 Yeo Woon Yoon et al.
