Abstract

N-rich porous organic polymers have shown promising application prospects in ion adsorption in the aqueous phase. Herein, an N-rich porous organic polymer (POP–N) was prepared via a one-step reaction and used as an adsorbent for the removal of La³⁺ from water. The interaction mechanism between POP-N and La³⁺ was revealed via spectroscopic analyses, nitrogen adsorption–desorption and adsorption model fitting. The results show that POP-N adsorbed 99 % of La³⁺ within 10 min. This was attributed to the abundant micropores and mesopores in POP-N and the presence of pyridine-N groups that strongly coordinated with La³⁺ within the pore structure. La³⁺ was found to rapidly enter POP-N, interact with adsorption sites in pores, and become enriched. This study is a valuable reference for developing efficient adsorbents based on N-rich porous organic polymers.

富n多孔有机聚合物对水中La3+的高效去除及其相互作用机理

富氮多孔有机聚合物在水相离子吸附方面具有广阔的应用前景。本文通过一步反应制备了富n多孔有机聚合物（POP-N），并将其用作水中La3+的吸附剂。通过光谱分析、氮吸附-解吸和吸附模型拟合揭示了POP-N与La3+的相互作用机理。结果表明，POP-N在10 min内吸附了99%的La3+，这是由于POP-N中存在丰富的微孔和介孔，并且在孔结构中存在与La3+强配位的吡啶- n基团。La3+可以快速进入POP-N，与孔隙中的吸附位点相互作用并富集。本研究为开发基于富氮多孔有机聚合物的高效吸附剂提供了有价值的参考。

期刊介绍： The Journal of Physics and Chemistry of Solids is a well-established international medium for publication of archival research in condensed matter and materials sciences. Areas of interest broadly include experimental and theoretical research on electronic, magnetic, spectroscopic and structural properties as well as the statistical mechanics and thermodynamics of materials. The focus is on gaining physical and chemical insight into the properties and potential applications of condensed matter systems. Within the broad scope of the journal, beyond regular contributions, the editors have identified submissions in the following areas of physics and chemistry of solids to be of special current interest to the journal: Low-dimensional systems Exotic states of quantum electron matter including topological phases Energy conversion and storage Interfaces, nanoparticles and catalysts.
