采用内耦合大块液膜分离技术, 通过考察料液相pH值、料液相NaCN浓度、载体浓度以及解析相NaOH浓度对Ag(Ⅰ)传输的影响, 研究了以维多利亚蓝(VB)为流动载体的液膜中银的传输规律, 并建立了渗透系数与pH值、 NaCN浓度以及载体浓度等之间的关系方程.结果表明, Ag(Ⅰ)以VB+*Ag(CN)2-离子缔合物形式在液膜中传输, 最佳传输条件为: 料液相中NaCN浓度为5.0×10-3 mol*L-1(pH=5.5), 解析相为0.05 mol*L-1 NaOH, 载体VB浓度为4.00×10-4 mol*L-1.Ni(Ⅱ), Co(Ⅱ), Zn(Ⅱ), Cu(Ⅱ), Pb(Ⅱ)及Cd(Ⅱ)离子对Ag(Ⅰ)传输无影响.
