Determinations In Reducing Degree Of Iron-Amine Complex By Cyclic Voltammetry, Yu-Kun Lai, Wei Wang
Determinations In Reducing Degree Of Iron-Amine Complex By Cyclic Voltammetry, Yu-Kun Lai, Wei Wang
Journal of Electrochemistry
The veracity and influence factors in reducing degree on iron-amine complex were tested by cyclic voltammetry.The types of cathode electrolytes including ferric nitrate,triethanolamine,sodium hydroxide and calcium nitrate were optimized.Compared with dip-dyeing coloration method,the cyclic voltammetry method can be used to measure the reducing degree of iron-amine complex more accurately with better stability,easier and faster operation.Potential applications of cyclic voltammetric determination method can be found in the fields of electrochemical dye production and related quality control.
Electrooxidation Of Methanol On Multilayer Films Of Polypyrrole-Platinum Electrode, Ling Zhang, Long-Zhen Zheng
Electrooxidation Of Methanol On Multilayer Films Of Polypyrrole-Platinum Electrode, Ling Zhang, Long-Zhen Zheng
Journal of Electrochemistry
Multilayer films of polypyrrole-platinum electrode were fabricated by cyclic voltammetric technique.Electro-oxidation of methanol on this electrode was investigated with the aid of cyclic voltammetry and chronoamperometry.Results demonstrated that the multilayer of polypyrrole-platinum electrode behaved better electrocatalytic performance for electro-oxidaton of methanol and better poison resistant.Furthermore,with the increase of deposited platinum loadings,the rate controlling step on electro-oxidation reaction of methanol was changed from CO oxidation to sorption-desorption of hydrogen.
