Phosphorus removal using nanofiltration membranes

Water Science and Technology, 2011
A high concentration of phosphorus in wastewater may lead to excessive algae growth and de-oxygenation of the water. In this work, nanofiltration (NF) of phosphorus-rich solutions is studied in order to investigate its potential in removing and recycling phosphorus. Wastewater samples from a pulp and paper plant were first analyzed.

Acid Resistant and Highly Silver Selective Membranes Based on Charged Nanoporous 2D‐Materials

Small, EarlyView.
In this work, new membranes based on charged & nanoporous nanosheets with unprecedented selectivity to silver versus a wide range of other metallic ions are reported. Furthermore, a demonstrated and lead specific intralamellar lead pathway is demonstrated. A potential applicability for ubiquitous silver in WEEE is validated.

Electroconductive MXene‐Thin‐Film‐Composite Membranes for Coupled Osmotic Concentration and PFAS Mineralization

Small, EarlyView.
An electroconductive MXene‐TFC membrane integrates osmotic dewatering with anodic oxidation to concentrate and mineralize PFOA at the membrane interface. The coupled AO‐PRO configuration accelerates degradation kinetics, achieves 99% rejection and up to 93% TOC removal, and lowers specific energy demand, offering a compact route for PFAS destruction ...

Preparation of Hydrophilic Polysilsesquioxanes and Their Applications as Water Separation and Antifogging Coating Materials

The Chemical Record, EarlyView.
Hydrophilic substituents were introduced onto the silicon atoms of random polysilsesquioxanes (PSQs) to improve water permeability and absorptivity for exploring the applications of PSQ materials as heat‐ and chlorine‐resistant water desalination reverse osmosis (RO) membranes and scratch‐resistant antifogging coating materials.
