Polyethersulfone-sulfonated polyethersulfone (PES-SPES) membranes were prepared by non-solvent immersion precipitation method, and then the graphene oxide-polydopamine (GO-PDA)/PES-SPES adsorptive membranes were fabricated by the stepwise in-situ growth method, and employed for the removal of rhodamine B (RhB) from aqueous solutions. The static adsorption thermodynamics, the effects of pH values, adsorption kinetics, and dynamic adsorption/desorption were investigated. The results showed that, the adsorption of RhB on the membrane can be well described by the Langmuir model and the pseudo-second-order kinetic model, and the maximum adsorption capacity of the GO-PDA layer is 87.03 mg g⁻¹, indicating a chemisorption dominated adsorption process. The GO adsorbents and PDA crossslinker contributed to the synergistic adsorption. The adsorptive membranes also exhibited good reusability in dynamic adsorption/desorption cycles.

采用非溶剂浸渍沉淀法制备聚醚砜-磺化聚醚砜（PES-SPES）膜，然后采用逐步原位生长法制备氧化石墨烯-聚多巴胺（GO-PDA）/PES-SPES吸附膜，并用于从水溶液中去除罗丹明 B (RhB)。研究了静态吸附热力学、pH 值的影响、吸附动力学和动态吸附/解吸。结果表明，RhB在膜上的吸附可以通过Langmuir模型和准二级动力学模型很好地描述，GO-PDA层的最大吸附容量为87.03 mg g ^-1，表明化学吸附占主导地位的吸附过程。GO 吸附剂和 PDA 交联剂有助于协同吸附。吸附膜在动态吸附/解吸循环中也表现出良好的可重复使用性。
