| 摘 要： | 研究了明胶对阴极极化、电流效率、电解液比电阻的影响，研究了在电解过程中明胶的电析消失现象，探讨了明胶的作用机理。研究表明：明胶能增大阴极过电位，能提高阴极电流效率，提高电解液的比电阻。明胶的电析消失速度随电流密度的增大而增大。明胶极有可能与In^3 形成络合物的形式参与电解过程。

| Abstract: | Effect of gelatin on cathodic polarization,current efficiency, and specific resistance was described, and mechanism of gelatin in electrolytic refining was also studied. The study shows that gelatin can increase cathodic superpotential,cathodic current efficiency and specific resistance. The consumption of gelatin increases when current density increases. It is proposed that gelatin plays a role as an agent of complexation with indium ion in electrolytic refining. |
