在盐酸体系中采用膜电解电溶法处理含镍、铬的铁基高温合金。通过优化条件,确定了膜电解过程的操作条件。研究结果表明,在电压为1.5 V、平均电流密度为500 A/m2、Ni2+离子浓度为1 mol/L、阳极液酸度为1 mol/L、极距为20 mm、温度为35℃条件下电解,电流效率可达90%以上,能耗为1 200 kW.h/t左右。 In the hydrochloric acid system using electrolytic membrane electrolysis nickel, chromium iron-based superalloy. By optimizing the conditions, the operating conditions of the membrane electrolysis process were determined. The results show that under the condition of a voltage of 1.5 V, an average current density of 500 A / m2, a concentration of Ni2 + ions of 1 mol / L, an acidity of 1 mol / L in anolyte, a pole pitch of 20 mm and a temperature of 35 ℃, , Current efficiency up to 90%, energy consumption of 1 200 kW.h / t or so.
