Abstract

Laminar graphene oxide (GO) membranes have demonstrated great potential as next-generation water-treatment membranes because of their outstanding performance and physicochemical properties. However, solute rejection and stability deterioration in aqueous solutions, which are caused by enlarged nanochannels due to hydration and swelling, are regarded as serious issues in the use of GO membranes. In this study, we attempt to use the crosslinking of divalent cations to improve resistance against swelling in partially reduced GO membranes. The partially reduced GO membranes intercalated by divalent cations (i.e., Mg) exhibited improved dye-rejection efficiencies of up to 98.40%, 98.88%, and 86.41% for methyl orange, methylene blue, and rhodamine B, respectively. In addition, it was confirmed that divalent cation crosslinking and partial reduction could strengthen mechanical stability during testing under harsh aqueous conditions (i.e., strong sonication).

摘要

层状氧化石墨烯（GO）膜因其出色的性能和物理化学性质，已展现出作为下一代水处理膜的巨大潜力。然而，由于水合作用和溶胀导致纳米通道扩大，从而引起的水溶液中溶质截留率和稳定性下降，被视为GO膜使用过程中的严重问题。在本研究中，我们尝试利用二价阳离子交联来提高部分还原的GO膜的抗溶胀性。由二价阳离子（即Mg）插层的部分还原GO膜，对甲基橙、亚甲基蓝和罗丹明B的染料截留效率分别提高至98.40%、98.88%和86.41%。此外，已证实二价阳离子交联和部分还原可增强在苛刻水相条件（即强烈超声处理）下测试期间的机械稳定性。
