Selective phosphate removal with manganese oxide composite anion exchange membranes in membrane capacitive deionization

Published: Feb. 26, 2024

The discharge of excessive phosphorous into water bodies can lead to serious eutrophication threatening aquatic ecosystem. Membrane capacitive deionization (MCDI) is an effective platform for deionizing aqueous streams; however, conventional MCDI unable selectively remove targeted ions from a liquid mixture. In this work, we fabricated manganese oxide composite anion exchange membranes (AEMs) enhance phosphate removal selectivity sodium chloride-sodium dihydrogen (10:1 molar ratio) mixtures. We systematically investigated several critical factors, such as constant current or voltage operation, applied amount, process stream pH, and content in the AEM, on efficiency selectivity. A trade-off was observed between when increasing cell voltage. Under best conditions, unit with 20 wt% Mn2O3 AEM bipolar membrane facilitated high ≥ 31.8 % over chloride 1.1 while showing stability at least 30 cycles. To help understand how particles boost selectivity, static electronic structure calculations were performed, they revelated that hydrogen absorption 314 kcal/mol more exothermic than pristine adsorption 2.2 less AEM. Overall, work presents strategy removing model wastewater solutions mechanistic understanding governs ion ion-exchange used MCDI.

Membrane capacitive deionization (MCDI) is an emerging water desalination platform that compact, electrified, and does not require high‐pressure piping. Herein, highly conductive poly(phenylene alkylene) ion‐exchange membranes (IEMs) are micropatterned with different surface geometries for MCDI. The increase the interfacial area liquid stream leading to a 700 mV reduction in cell voltage when operating at constant current (2 mA cm −2 ; 2000 ppm NaCl feed) while improving energy normalized adsorbed salt (ENAS) value by 1.4 times. Combining IEMs ionomer‐filled electrodes reduces 1000 improves ENAS values 2.3 times relative base case. This allows higher density operation (i.e., 3–4 ) . ascribed ameliorating ohmic resistances related ion transport membrane‐process interface carbon cloth electrode. Finally, porous ionic conductors implemented into spacer channel flat IEM configurations ionomer infiltrated electrodes. For configuration IEMs, conductor across regime (2–4 ), it gets improved only 4
