A Study on Adsorption of Electrogenerated Cystine Precipitate onto An Electrode using Electrochemical Quartz Crystal Impedance System

Chemical Research Institute Hunan Normal University Changsha 410081

Received Date: 15 July 1999

An electrochemical quartz crystal impedance system has been applied to monitor generation of precipitate and adsorption of the precipitate onto Au electrode during electrochmical oxidation and Fe(CN)₆^3-/Fe(CN)₆^4- electrochemical catalytic oxidation of L-cysteine in phosphate aqueous buffer (pH 7.4). Significant decreases in the resonant frequency and increases in the motional resistance and the static capacitance were found during the precipitate adsorption, and the frequency shift found in solution was ca. 2 times that in air. Similar responses of quartz crystal impedance and a white precipitate were obtained during redox titration of L-cysteine solution using K₃Fe(CN)₆ solution. FT-IR analysis indicated that the white precipitate is cystine. The electrode collection efficiency of the electrogenerated cystine was estimated.
