Abstract:
It is imperative to devise effective removal strategies for high ionization potential (IP) organic pollutants in wastewater as their reduced electron-donating capacity challenges the efficiency of advanced oxidation systems in degradation. Against this backdrop, leveraging the metal-based carbon material structure meticulously, we employed metal-pyridine-N (M-N-C, M=Fe, Co, and Ni) as the electron transfer bridge. This distinctive design facilitated the ordered transfer of electrons from the adsorbent surface to the surface of high IP value pollutants, acting as a \"supplement\" to compensate for their deficient electron-donating capability, thereby culminating in the selective adsorption of these pollutants. Furthermore, this adsorbent also demonstrated effective removal of trace emerging contaminants (2 mg/L), displayed robust resistance to various salts, exhibited reusability, and maintained stability. These findings carry substantial implications for future carbon-based material design, offering a pathway toward exceptional adsorption performance in treating water pollution.
摘要:
必须为废水中的高电离电位(IP)有机污染物设计有效的去除策略,因为它们的电子供给能力降低了高级氧化系统的降解效率。在这种背景下,精心利用金属基碳材料结构,我们使用金属-吡啶-N(M-N-C,M=Fe,Co,和Ni)作为电子转移桥。这种独特的设计促进了电子从吸附剂表面到高IP值污染物表面的有序转移,作为“补充”来弥补它们不足的电子供给能力,从而最终导致这些污染物的选择性吸附。此外,该吸附剂还显示出有效去除痕量新出现的污染物(2mg/L),对各种盐表现出强大的抵抗力,表现出可重用性,并保持稳定。这些发现对未来的碳基材料设计具有重要意义。为处理水污染提供了一条通往卓越吸附性能的途径。
