Abstract

Background: The wastewater released from various industries contains substantial amounts of organic compounds such as dyes and naphthols. However, naphthols are toxic to the environment and human health. So, it is essential to eliminate them, which will contribute to manufacturing and environmental management. Methods: In the work, an eco-friendly method is adapted to synthesize reduced graphene oxide (rGO) using Equisetum arvense plant extract as a strong reducing and stabilizing agent. Then, a hybrid nano adsorbent based on rGO and ordered mesoporous carbon (CMK-3) decorated with iron oxide nanoparticles (Fe3O4@rGO/CMK-3) was prepared as an adsorbent. We investigate the performance of Fe3O4@rGO/CMK-3 to remove 2-naphthol (2-NP). Results: The FE-SEM images exhibited spherical magnetite nanoparticles with sizes ranging from 31 to 47 nm on composite. Efficient removal (90%) of 2-NP from aqueous solution is demonstrated using high surface area Fe3O4@rGO/CMK-3 (initial concentration of 2-NP: 10 mg mL-1, pH: 5.0, time: 30 min, and amount of adsorbent dosage: 3 mg mL-1). The high surface area of Fe3O4@rGO/CMK-3, hydrogen binding, π-π stacking interaction between the benzene rings of 2-NP and graphitic skeleton of hybrid adsorbent facilitate the adsorption of 2-NP on the Fe3O4@rGO/CMK-3. The 2NP removal capacity by Fe3O4@rGO/CMK-3 showed a significant decrease during five successive cycles. Conclusions: These results promise the potential of high surface area Fe3O4@rGO/CMK-3 for efficient removal of 2-NP for wastewater treatment.

磁铁矿还原石墨烯氧化物/有序介孔碳纳米复合材料作为去除废水中 2-萘酚的有效吸附剂

背景：各种工业排放的废水中含有大量有机化合物，如染料和萘酚。然而，萘酚对环境和人类健康有毒。因此，必须消除它们，这将有助于生产和环境管理。方法：在这项工作中，采用了一种生态友好型方法，以马钱子植物提取物作为强还原剂和稳定剂，合成还原型氧化石墨烯（rGO）。然后，制备了一种基于还原氧化石墨烯和有序介孔碳（CMK-3）并装饰有氧化铁纳米颗粒（Fe3O4@rGO/CMK-3）的混合纳米吸附剂。我们研究了 Fe3O4@rGO/CMK-3 去除 2-萘酚（2-NP）的性能。结果：FE-SEM 图像显示，复合材料上的磁铁矿纳米颗粒呈球形，大小为 31 至 47 nm。使用高比表面积的 Fe3O4@rGO/CMK-3（2-NP 的初始浓度为 10 mg mL-1，pH 值为 5.0，吸附时间为 30 分钟，吸附量为 0.5 mg mL-1）可以有效去除水溶液中的 2-NP（90%）：30 分钟，吸附剂用量为 3 mg mL-1）：3 毫克毫升-1）。Fe3O4@rGO/CMK-3 的高比表面积、氢结合、2-NP 苯环与杂化吸附剂石墨骨架之间的 π-π 堆积相互作用促进了 2-NP 在 Fe3O4@rGO/CMK-3 上的吸附。在连续五个循环中，Fe3O4@rGO/CMK-3 对 2-NP 的去除能力显著下降。结论：这些结果证明了高比表面积 Fe3O4@rGO/CMK-3 在废水处理中高效去除 2-NP 的潜力。

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
