研究了以循环伏安法测定铁胺络合物还原强度的准确度及其影响因素,优化阴极电解液(包括硝酸铁、三乙醇胺、氢氧化钠、硝酸钙).实验表明,由循环伏安法测定的铁胺络合物还原强度与浸染染色法测得的比较,前者准确度好、稳定性高,而且操作方便快捷,在电化学还原染色生产和质量控制中具有重要的应用价值.
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.
