Magnetically separated and N, S co-doped mesoporous carbon microspheres (NIS-MCMs/Fe304) are fabricated by encapsulating Si02 nanoparticles within N, S-containing polymer microspheres which were prepared using resorcinol/formaldehyde as the carbon source and cysteine as the nitrogen and sulfur co-precursors, followed by the carbonization process, silica template removal, and the introduction of Fe3O4 into the carbon mesopores. N/S-MCMs/Fe3O4 exhibits an enhanced Hg2+ adsorption capacity of 74.5 rag/g, and the adsorbent can be conveniently and rapidly separated from wastewater using an external magnetic field. This study opens up new opportunities to synthesize well- developed, carbon-based materials as an adsorbent for potential applications in the removal of mercury ions from wastewater. 展开更多
