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.
