The effects of dihexadecyl phosphate(DHP) and multi-walled carbon nanotubes(MWNTs) on the oxidation of guanine mediated by[Ru(bpy)3]2+ on the ITO electrode have been investigated by cyclic voltammetry and differential pulse voltammetry.The results showed that [Ru(bpy)3]2+ can mediate the oxidation.In the range from 0.01 to 0.15 mmol·L-1,peak currents for guanine oxidation mediated by [Ru(bpy)3]2+ increased with the rise of DHP concentrations.On the contrary,cationic surfactant HTAC has the ability to weaken the mediated oxidation of guanine.In addition,the oxidative mechanism of guanine mediated by [Ru(bpy)3]2+ with the participation of DHP is discussed.

The existence of electrochemical reaction during the corrosion process of pure Fe under a deposit of solid NaCl in water vapor at above 400 ℃ had been detected by measuring the corrosion current using double-layer electrode.In EIS measurement,only one capacitive loop was obtained on the pure metals and this gave the information of oxide layer on them.The electrochemical impedance spectroscopy(EIS) and scanning-electron microscopy(SEM) results testified that there is a good relationship between the resistance of oxide layer Rox and the corresion reaction rate for pure metals with different oxidation times.The electrochemical technique is an effective method for studying corrosion performance …
