Abstract:
Objective Electrochemical pretreatment method was used tomodify glassy carbon electrode(CCE) and investigate the electrochemical character of SCN
-.
Methods A novel electrochemically pretreated CCE(PCCE)was achieved by anodic oxidation at a higher potential,followed by potential cyclic scanning in a widerpotential Electrochemical character of SCN
- was investigated and deteun fined with the electrode.
Results The reaction of SCN
- on PCCE was an it reversible adsorption process.The oxidation peak currents were linearwith the concentration of SCN
- within a range from 6.7×10
-6~6.7×10
-4mol/L.The detection lin it of SCN
- was 3.3×10
-6 mol/L.
Conclusion The PCCE can be used to detercn fine trace SCN
-.
