Electrochemical Behavior of Thiocyanate Acid-PPy Modified Electrode

The compound assemble function of Hg²⁺ by SCN^--PPy film modified electrode is reported.Electrochemical behavior and factors that affect the response character of the CME is studied,and the response mechanism of the CME is discussed.The oxidation peak current at 0.46v is in direct proportion to concentration of Hg²⁺ during 8.0×10^-6 and 5.0×10^-8 mol/L.The mehtod is applied to determine Hg²⁺ in waste water.
