Abstract: To study environment-friendly determination of azobenzene in trace amounts using β-cyclodextrin (β-CD)-modified Au electrode.Methods β-CD-modified Au electrode was fabricated with a two-step approach,and then a gold electrode modified with β-CD was used to detect azobenzene by employing Osteryoung square wave voltammetry.Results The modified electrode could detect azobenzene,showing a good linearity between the electrochemical current and concentration.Conclusion Although the electrochemical current is related with concentration,the detection limit is around 1.0×10-10 mol/L.This study may provide a new environment-friendly approach for monitoring water quality.
