Environmental Science & Technology, Год журнала: 2022, Номер 56(18), С. 12811 - 12827

Опубликована: Сен. 1, 2022

Nanofiltration (NF) membranes have been widely applied in many important environmental applications, including water softening, surface/groundwater purification, wastewater treatment, and reuse. In recent years, a new class of piperazine (PIP)-based NF featuring crumpled polyamide layer has received considerable attention because their great potential for achieving dramatic improvements membrane separation performance. Since the report novel Turing structures that exhibited an order magnitude enhancement permeance ( Science 2018, 360 (6388), 518−521), number published research papers on this emerging topic grown exponentially to approximately 200. critical review, we provide systematic framework classify morphologies. The fundamental mechanisms fabrication methods involved formation these morphologies are summarized. We then discuss transport solutes how phenomena could simultaneously improve permeance, selectivity, antifouling applications highlighted, future opportunities/needs identified. insights review guidance further development high-performance tailored wide range applications.

The coming of age of water channels for separation membranes: from biological to biomimetic to synthetic

Chemical Society Reviews, Год журнала: 2022, Номер 51(11), С. 4537 - 4582

Опубликована: Янв. 1, 2022

Water channels are one of the key pillars driving development next-generation desalination and water treatment membranes. Over past two decades, rise nanotechnology has brought together an abundance multifunctional nanochannels that poised to reinvent separation membranes with performances exceeding those state-of-the-art polymeric within water-energy nexus. Today, these can be broadly categorized into biological, biomimetic synthetic, owing their different natures, physicochemical properties methods for membrane nanoarchitectonics. Furthermore, against backdrop mechanisms, types nanochannel exhibit unique merits limitations, which determine usability suitability designs. Herein, this review outlines progress a comprehensive amount nanochannels, include aquaporins, pillar[5]arenes, I-quartets, nanotubes porins, graphene-based materials, metal- covalent-organic frameworks, porous organic cages, MoS2, MXenes, offering comparative glimpse where potential lies. First, we map out background by looking evolution over years, before discussing latest developments focusing on intrinsic transport from chemistry standpoint. Next, put perspective fabrication nanoarchitecture high-performance nanochannel-enabled membranes, especially distinct differences each type how they leveraged unlock as-promised high in current mainstream Lastly, critically evaluate recent findings provide holistic qualitative assessment respect attributes most strongly valued engineering, upcoming challenges share our perspectives researchers pathing future directions coming age channels.

Novel Positively Charged Metal-Coordinated Nanofiltration Membrane for Lithium Recovery

ACS Applied Materials & Interfaces, Год журнала: 2021, Номер 13(14), С. 16906 - 16915

Опубликована: Апрель 2, 2021

Nanofiltration (NF) with high water flux and precise separation performance Li+/Mg2+ selectivity is ideal for lithium brine recovery. However, conventional polyamide-based commercial NF membranes are ineffective in recovery processes due to their undesired selectivity. In addition, they constrained by the permeance trade-off, which means that a highly permeable membrane often has lower this study, we developed novel nonpolyamide based on metal-coordinated structure, exhibits simultaneously improved Specifically, optimized Cu–m-phenylenediamine (MPD) demonstrated of 16.2 ± 2.7 LMH/bar 8.0 1.0, surpassed trade-off Meanwhile, existence copper Cu–MPD further enhanced anti-biofouling property nanofiltration possesses pH-responsive property. Finally, transport model Nernst–Planck equations been fit rejection uncharged solutes experiments conducted.
