研究了在Ｐ５０７－ＣＣｌ４大块液膜体系中，载体Ｐ５０７浓度、反萃液硫酸的浓度、料液ｐＨ、醋酸根浓度等因素对Ｃｏ２＋的活性迁移的影响．实验结果表明，载体浓度增加，Ｃｏ２＋的迁移通量增加．反萃液硫酸浓度增加，料液ｐＨ及醋酸根浓度适度增加均有利于Ｃｏ２＋的迁移．实验中观察到Ｃｏ２＋在膜迁移中的滞留现象，并在支撑液膜实验中测定了较大的Ｐ５０７浓度时Ｃｏ２＋的渗透系数Ｐ．
In the P507-CCl4 bulk liquid membrane system, the effect of P507 carrier concentration, stripping solution sulfuric acid concentration, feed solution pH, acetate concentration and other factors on the activity of Co2 + migration. The experimental results show that the carrier concentration increases and the migration flux of Co2 + increases. Stripping sulfuric acid concentration increased, feed liquid and acetate concentration moderate increase are conducive to the migration of Co2 +. In the experiment, the phenomenon of Co2 + retention in the membrane migration was observed and the permeability coefficient P of Co2 + at the larger P507 concentration was measured in the support liquid membrane experiment.
