Influence of oxidation stage and exfoliation extent of carbon-based materials on electrochemical detection of As(III)
Original language description
This study deals with the electrochemical detection of As(III) and especially with its in-teraction with carbon-based materials such as graphene oxide, graphite oxide and partially reduced graphene oxide in connection with the adsorption of As(III) to their surface. Using differential pulse voltammetry, it was found that the As(III) reaches the best adsorption efficiency on the carbon-based materials surfaces at very acidic pH after interaction time 1 hour. We decided to use this promising ability of graphene oxide to design a new method for As(III) detection using a modified glassy carbon electrode. In order to enable detection of As(III) the surface of glassy carbon electrode was firstly modified by gold nanoparticles (AuNPs). After this step the working electrode was modified for a second time by graphene oxide to enhance the electrochemical signal of As(III). Compared to the working electrode modified only by gold nanoparticles, the electrochemical signal of As(III) on the GCE/AuNP
