Heavy metals pose a significant threat to ecosystems and human health because of their toxic properties ability bioaccumulate in living organisms. Traditional removal methods often fall short terms cost, energy efficiency, minimizing secondary pollutant generation, especially complex environmental settings. In contrast, molecular simulation offer promising solution by providing in-depth insights into atomic interactions between heavy potential adsorbents. This review highlights the for removing types pollutants science, specifically metals. These powerful tool predicting designing materials processes remediation. We focus on specific like lead, Cadmium, mercury, utilizing cutting-edge techniques such as Molecular Dynamics (MD), Monte Carlo (MC) simulations, Quantum Chemical Calculations (QCC), Artificial Intelligence (AI). By leveraging these methods, we aim develop highly efficient selective unravelling underlying mechanisms, pave way developing more technologies. comprehensive addresses critical gap scientific literature, valuable researchers protection health. modelling hold promise revolutionizing prediction metals, ultimately contributing sustainable solutions cleaner healthier future.

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.
