摘要
Abstract
The electrochemical reduction of Vat Scarlet R was carried out in electrolytic equipment with graphite as anode and cathode [adding 15 g/L H2SO4 in the anodic cell as the electrolyte and adding Fe2(SO4)3, NaOH, C2H2O4, CafCeHnOy^ in the cathodic cell as the reductant dye liquor]. The results showed that good dyeing effect could be obtained under the follow condition: Vat Scarlet R 4 g/L, Fe^SOJs 8 g/L, NaOH 50 g/L, C2H2O412.6 g/L, Ca(C6H11O7)2 24.4 g/L, voltage 4 V, the reducing time 10 min, area of cathode 40 cm2.关键词
