摘要

An expanding area of green technology is the wastewater treatment of heavy metal ions. As the adsorption of cations onto solid surfaces has been proven to be successful, recent research has demonstrated enhanced adsorption profiles by grafting dendron brushes onto a solid support. Via the molecular dynamics technique, we examine the adsorption of Pb(II) ions onto polyamidoamine (PAMAM) with carboxylate terminal groups through a coarse-grained implicit solvent model. We identify dendron generations and grafting densities, or surface coverage levels, which demonstrate optimal adsorption of Pb(II) ions. Our results can be potentially used to design functionalized surfaces for metal ion adsorption in application entailing environmental remediation or protective surface coating.

Physical Chemistry Chemical Physics (PCCP) is an international journal co-owned by 19 physical chemistry and physics societies from around the world. This journal publishes original, cutting-edge research in physical chemistry, chemical physics and biophysical chemistry. To be suitable for publication in PCCP, articles must include significant innovation and/or insight into physical chemistry; this is the most important criterion that reviewers and Editors will judge against when evaluating submissions. The journal has a broad scope and welcomes contributions spanning experiment, theory, computation and data science. Topical coverage includes spectroscopy, dynamics, kinetics, statistical mechanics, thermodynamics, electrochemistry, catalysis, surface science, quantum mechanics, quantum computing and machine learning. Interdisciplinary research areas such as polymers and soft matter, materials, nanoscience, energy, surfaces/interfaces, and biophysical chemistry are welcomed if they demonstrate significant innovation and/or insight into physical chemistry. Joined experimental/theoretical studies are particularly appreciated when complementary and based on up-to-date approaches.
