A series of metal-azolate frameworks or MAFs-MAF-4, -5, and -6-were synthesized and pyrolyzed to prepare porous carbons derived from MAFs (CDM-4, -5, -6, respectively). Not only the obtained carbons but also MAFs were characterized and applied for the adsorption of organic contaminants of emerging concern (CECs, including pharmaceuticals and personal care products) such as salicylic acid, clofibric acid, diclofenac sodium, bisphenol-A, and oxybenzone (OXB) from water. CDM-6 was found to be the most remarkable adsorbent among the tested ones (including activated carbon) for all the adsorbates. OXB was taken as a representative adsorbate for detailed adsorption studies as well as understanding the adsorption mechanism. H-bonding (H-acceptor: CDM; H-donor: CECs) was suggested as the principal mechanism for the adsorption of tested adsorbates. Finally, CDMs, especially CDM-6, were suggested as highly efficient and easily recyclable adsorbents for water purification.
一系列金属-氮杂环框架或 MAFs（MAF-4、-5 和-6）被合成并热解，以制备源自 MAFs 的多孔碳（分别为 CDM-4、-5 和-6）。不仅获得的碳，而且 MAFs 都进行了表征，并应用于从水中吸附新兴关注的有机污染物（CECs，包括药物和个人护理产品），如水杨酸、氯菲酸、双氯芬酸钠、双酚 A 和氧苯酮（OXB）。在所有的吸附剂中，CDM-6 被发现是测试过的（包括活性炭）中最显著的吸附剂。OXB 被选为代表性的吸附物，以进行详细的吸附研究以及了解吸附机制。氢键（H-受体：CDM；H-供体：CECs）被认为是测试吸附物吸附的主要机制。最后，建议将 CDMs，特别是 CDM-6，作为高效且易于回收的水净化吸附剂。
