| Abstract: | The PPy/STAB-MMT/GC electrode was made using montmorillonite modified by STAB and polypyrrole(PPy).The electrochemical behaviors of hydroquinone on the PPy/STAB-MMT/GC electrode were researched by cyclic voltammetry and square wave stripping voltammetry(SWSV).The results showed that the electrode reaction occurred on the hydroquinone electrode was controlled by diffusion in PBS(pH=6.0).The number of electron transfer was equal to the number of protons(n=m=1) with the effective area of PPy/STAB-NaMMT/GC electrode Aeff=0.031 cm2.Under the optimized conditions,the linear response of peak current in SWSV with the concentration of hydroquinone in a range of 8.0×10-6~8.0×10-4 mol/L was observed,and the detect limitation was 1.0×10-6 mol/L.The recovery of hydroquinone to testing requirements was satisfactory. |
