The selective removal of Cu(II) in the presence of sodium dodecylobenzene sulfonate from acidic effluents was made using the adsorption and micellar-enhanced ultrafiltration methods. Lewatit MonoPlus TP220 showed the best adsorption behavior in the systems containing Cu(II) in the presence of ABSNa50 surfactant compared to the other adsorbents (removal efficiency ≈ 100%, sorption capacity ≈ 10 mg/g). The kinetics followed the pseudo-second order kinetic equation. The Langmuir adsorption capacities were 110 mg/g (the system with ABSNa50 above CMC) and 130.38 mg/g (the system with ABSNa50 below CMC). The working ion exchange capacities were = 0.0216 g/mL and = 0.0135 g/mL. The copper removal by the micellar-enhanced ultrafiltration method was 76.46% (0.1 mol/L HCl).
采用吸附和胶束强化超滤法，在十二烷基苯磺酸钠存在下从酸性废水中选择性去除 Cu(II)。与其他吸附剂相比，Lewatit MonoPlus TP220 在含有 Cu(II)和 ABSNa50 表面活性剂的体系中表现出最佳的吸附行为（去除效率≈100%，吸附容量≈10 mg/g）。动力学遵循准二级动力学方程。Langmuir 吸附容量分别为 110 mg/g（CMC 以上的 ABSNa50 体系）和 130.38 mg/g（CMC 以下的 ABSNa50 体系）。工作离子交换容量分别为 = 0.0216 g/mL 和 = 0.0135 g/mL。胶束强化超滤法去除铜的效率为 76.46%（0.1 mol/L HCl）。
