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.
