Abstract
- Multiwalled carbon nanotubes/polydopamine/gold nanoparticles composite (MWCNTs/PDA/AuNPs) was synthetized successfully.
- A novel electrochemical sensor for simultaneous determination of hydroquinone and catechol based on MWCNTs/PDA/AuNPs and chitosan was developed.
- The peak potential of the oxidation peaks of HQ and CC were at 192Â mV and 297Â mV, respectively, indicating an anodic ÎEp of 105Â mV, which is wide enough to separate the two components.
- The sensor showed wide linear responses for HQ and CC with detection limits of 35Â nM and 47Â nM, respectively.
