摘要

高效去除低浓度内分泌干扰物对保护水生环境至关重要。本研究采用纳秒脉冲放电等离子体对多孔聚合物吸附材料进行改性，以实现对低浓度双酚 A（BPA）的高效吸附。在 28 kV 的脉冲峰值电压下，等离子体改性 10 分钟后，双酚 A 的去除率达到 99%，与原材料相比提高了 25.8%。这种提高归因于活性位点和含氧官能团的增加。多孔聚合物材料的吸附行为主要以单层化学吸附为主。随后的对比实验进一步验证了多孔聚合物材料经等离子处理后的高效吸附性能。

Nanosecond pulsed discharge plasma modified porous polymer adsorbent materials for efficient removal of low‐concentration bisphenol A in liquid

The efficient removal of low‐concentration endocrine disruptors is crucial for the protection of the aquatic environment. In this study, porous polymer adsorbent materials were modified by nanosecond pulsed discharge plasma to achieve efficient adsorption of low‐concentration bisphenol A (BPA). The removal efficiency of BPA reached 99% after 10 min of plasma modification at a pulse peak voltage of 28 kV, which increased by 25.8% compared to the raw materials. This enhancement was attributed to the increase of active sites and oxygen‐containing functional groups. The adsorption behaviors of the porous polymer materials were primarily dominated by monolayer chemisorption. Subsequently, comparative experiments further verified the high‐efficiency adsorption performance of porous polymer materials after plasma treatment.
