Hierarchical Membrane for Photoelectrostatically Gated Monovalent‐Divalent Ion Separation

Angewandte Chemie International Edition, EarlyView.
We report a hierarchical poly(ionic liquid)–carbon nitride membrane supported on anodic alumina for efficient monovalent/divalent ion separation. Confined nanochannels and tailored interfacial ion interactions enable exceptional K+/Mg2+ ( > 500) and Li+/Mg2+ ( > 200) selectivities, offering a promising strategy for advanced aqueous ion separations ...

Salinity Reduction of Real Produced Waters via Assisted Reverse Electrodialysis

Chemical Engineering Transactions, 2023
Produced waters (PWs) are waste streams generated during the crude oil extraction processes. The management of these wastewaters is complicated by the large volumes extracted during the oil recovery operations: these depends on the life of the oil-well ...

Energy generation by reverse electrodialysis

IOP Conference Series: Materials Science and Engineering, 2020
Abstract In this work, the process of generating electricity from the water salinity gradient (RED) using the Russian produced ion exchange membranes MK-40 and MA-41 was investigated. The experiments were carried out with a saturated brine of sodium chloride in a chamber with salt water and with a solution of sodium chloride with a ...
