Chitosan-based porous composites embedded with molybdenum disulfide nanosheets for removal of mercury from wastewater.

Mercury-containing wastewater presents a significant environmental threat due to its high toxicity. Therefore, the urgent removal of mercury-laden wastewater is essential to protect ecosystems and public health. In this study, molybdenum disulfide (MoS) nanosheets modified with a silane coupling agent (designated as MS) were crosslinked with natural polymer chitosan (CS) rich in -NH and - OH groups to develop a highly efficient and environmentally friendly MoS-functionalized three-dimensional reticulated porous materials (denoted as MS/CTS) composite adsorbent.

A new Fe-C porous filter material from dredged sediment: preparation, characterization, and its application.

A new Fe-C porous filter material was prepared with dredged sediment of river as raw material. The orthogonal test L(3) and component ratio experiment of raw material were conducted to investigate the optimum technological condition. Further, the filter obtained was characterized by Brunauer-Emmett-Teller (BET), scanning electron microscopy (SEM), energy dispersive X-ray spectroscope (EDS), and X-ray diffraction (XRD).
