摘　　要：在无膜、阳离子膜和阴离子膜的电解槽中,通85mA的直流电1h后,探讨直流电对酸皮等电点、酸皮的湿热稳定性、酸皮的铬吸收性、蓝皮的染料和加脂剂吸收性的影响。研究发现,在无膜和阳离子膜时,酸皮的等电点有所降低,有阴离子膜时,等电点上升;阴离子膜正极区,酸皮的耐湿热稳定性提高得最多;阳离子膜正极区,酸皮对铬的吸收最高;阳离子膜负极区染料的吸收率最高;无膜电解时,坯革对磺化油的吸收最好。The electrolytic bath with non membrane, cationic membranes, anionic membranes was treated with 85 mA DC for 1 h, and isoelectric point of pickled pelts, Ts of pickled pelts, the absorptivity of Cr, absorptivity of dye, absorptivity of sulfonated oil were tested. The results show that isoelectric point of pickled pelt was dropt when the electrolytic bath was treated with non membrane and cationic membranes, and raised with anionic membranes; In anode with anionic membranes, Ts of pickled pelts improved the most; In anode with cationic membranes, the absorptivity of Cr was the highest; In cathode with cationic membranes, the absorptivity of dye was the highest; absorptivity of sulfonated oil was the best with non membrane.
