摘要
文章研究了在间接电化学还原过程中NaOH、Fe2(SO4)3、三乙醇胺(TEA)及阴极面积、外加电压、还原温度、时间等因素对还原大红R还原的影响。通过这些因素的影响规律,选择较好的还原工艺。
This text mainly analyses the effect of some factors,such as Sodium hydroxide, Ferric sulfate, triethanolamine, the area of cathode, voltage, temperature and time ect.for indirect electro- chemical reduction of vat scarlet R. Through the effects of these factors the better reductive process can be gained.
