ABSTRACT
<p><b>OBJECTIVE</b>To study environment-friendly determination of azobenzene in trace amounts using beta-cyclodextrin (beta-CD)-modified Au electrode.</p><p><b>METHODS</b>beta-CD-modified Au electrode was fabricated with a two-step approach, and then a gold electrode modified with beta-CD was used to detect azobenzene by employing Osteryoung square wave voltammetry.</p><p><b>RESULTS</b>The modified electrode could detect azobenzene, showing a good linearity between the electrochemical current and concentration.</p><p><b>CONCLUSION</b>Although the electrochemical current is related with concentration, the detection limit is around 1.0 x 10(-10) mol/L. This study may provide a new environment-friendly approach for monitoring water quality.</p>
