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-MMT/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 …

Electrochemical behaviors of Zn in 3mol•L-1 KOH solution containing the single additive( Pb(NO3)2 , SDBS )the mixed additives( Pb(NO3)2+SDBS ) were investigated. The results showed that all the additives can supress the corrosion of zinc in 3mol•L-1 KOH solution. And the inhibition effeciency of the mixed additives is higher than that of any single additive.
