Cesium-137 (Cs(I)) is highly hazardous in low-level wastewater and a major problem nuclear wastewater. Its effective removal from contaminated crucial to ensuring environmental safety public health. In this study, cesium ion-imprinted composite membranes (I-DBC) were developed for selective separation of Cs(I) using dopamine modification ion-imprinting techniques. Bacterial cellulose (BC) was used as carrier the membrane matrix, adsorption capacity material greatly improved after hydrophilic mimetic bonding ion blotting Rapid ions low concentration energy realized. The researchers conducted both static dynamic experiments on evaluate performance I-DBC membranes. results showed that more compatible with Langmuir model adsorbed mainly by chemical monolayer adsorption, maximum 50.016 mg g–1 under optimal conditions. wastewater, 4.093 g–1. Furthermore, during permeation experiments, breakthrough point approximately 20 min. demonstrated good flux properties, which underscores its potential practical application treatment findings suggest holds promising prospects efficient water, contributing safer management.

Abstract Molybdenum (Mo) serves as the key site in nitrogenase enzyme, catalyzing conversion of N 2 into NH 3 under ambient conditions. However, strong affinity Mo sites for hinders H adsorption due to competitive nature and on a single site, resulting an unsatisfactory ammonia synthesis performance. Here, we propose approach intervening C 60 layer second two‐dimensional CT x . The thickness is readily tunable by varying its loading content. An optimal significantly enhances electronic interaction between layer, leading remarkable decrease work function increase electron density atoms. Therefore, separate distinct substantially facilitated. present offers insights correlation structure performance catalysts.
