Abstract:

Membrane separation technology has become an important method for ion separation due to its advantages of low energy consumption and high selectivity. Graphene oxide (GO) exhibits single-atom thickness with fruitful oxygen-containing groups. The GO laminar membrane shows precise ion-sieving selectivity. This review systematically presents the progress of GO membranes for selective transport of ions. The performance of GO membranes is optimized by laminar structure regulation and charge modification. For laminar structure regulation, the methods of partial reduction, physical intercalation and chemical crosslinking are mainly used to enhance the size-sieving ability of GO membranes for selective ion transport. As for the charge modification method, the strategies of positive/negative-charge modifications are usually employed to tune the long-range electrostatic interaction between GO membranes and the guest ions. This review will deepen the understanding on the mechanism of the ion selectivity of GO membranes, and put forward to the research direction in order to promote the development of GO membrane in the application of ion separation.

摘要:

膜分离技术具有低能耗和高选择性的优势,已成为离子分离的重要手段。氧化石墨烯(GO)具有单原子厚度,表面富含多种含氧基团,利用其构筑的层叠膜展现出精确的离子筛分性能。本文系统地介绍了GO膜在离子选择性传递调控方面取得的研究进展,从层叠通道调控和电荷修饰两个角度对GO膜的离子选择性传递性能进行阐述。对于层叠通道,可采用部分还原法、物理插层法、化学交联法进行精确调控,实现GO膜对离子筛分性能的强化。对于电荷修饰,常采用正/负电荷改性策略对GO膜与离子间的长程静电作用进行调控。本文将深化对GO层叠膜离子选择性传递机制的认识,同时提出该领域的发展方向,以期促进GO膜在离子分离领域的进一步发展。
