Electrochemical investigation of anthraquinone-based chemodosimeter for [Cu.sup.2+] metal Ion

The electrochemical properties of an anthraquinone-containing [Cu.sup.2+]- promoted desulfurization chemodosimeter (AQCD) in the presence of various metal ions were investigated by voltammetry. AQCD showed voltammetric changes toward divalent metal ions ([M.sup.2+]), which are similar to those of anthraquinone (AQ) and 1- aminoanthraquinone (AQN[H.sub.2]) with the metal ions except [Cu.sup.2+]. This can be explained on the electrostatic interaction (AQCD-[M.sup.2+]) and chemodosimetric reaction (AQCD-[Cu.sup.2+]).
