Recently, contamination of water resources with phenolic compounds (PCs) is severe. In this study, we firstly prepared nitrogen-enriched porous carbon via pyrolysis of a mixture of melamine and polyaniline. Melamine/polyaniline-derived carbons (MPDCs) were characterized and applied in the adsorption of PCs, like p-nitrophenol (pNP), hydroquinone (HQ) and p-cresol (pC), from water. A selected MPDC700, an MPDC prepared at 700 ^oC, had the highest adsorption capacity for pNP (Q_max: 910±18 mg/g) and pC, compared with any known material. Based on the adsorption results under wide conditions and characteristics of MPDCs, the plausible adsorption mechanism, such as π-π interaction and hydrogen bonding, could be suggested. The best MPDC700 was recyclable for several runs; therefore, can be recommended as a competitive adsorbent to remove PCs from water.

最近，酚类化合物（PC）对水资源的污染严重。在这项研究中，我们首先通过热分解三聚氰胺和聚苯胺的混合物制备了富氮多孔碳。对三聚氰胺/聚苯胺衍生的碳（MPDC）进行了表征，并将其应用于从水中吸附PC，例如对硝基苯酚（pNP），对苯二酚（HQ）和对甲酚（pC）。选定的MPDC700（在700 ^o C下制备的MPDC）对pNP的吸附能力最高（Q _max：910±18 mg / g）和pC，与任何已知材料相比。根据在大范围条件下的吸附结果和MPDC的特性，可以提出合理的吸附机理，如π-π相互作用和氢键。最好的MPDC700可循环使用多次。因此，可以推荐作为从水中去除PC的竞争性吸附剂。
