Magnetic Mesoporous Carbon

In this work, a novel N-doped magnetic mesoporous carbon (NMC) composite (Fe3O4/NMC) was synthesized by a two-step process. First, NMC was prepared by a template method using a melamine formaldehyde resin as nitrogen and carbon sources, and then, Fe3O4 nanoparticles were loaded into the as-prepared NMC via in-situ coprecipitation process. The morphology, structure, and magnetic properties of Fe3O4/NMC were characterized and its adsorption properties were investigated. It can be found that Fe3O4/NMC with saturation magnetization of 20 emu · g−1 features a mesoporous structure, and its specific surface area reaches 513 m2 · g−1. These two excellent specificities are propitious to the adsorption and separation of Ag(I) from aqueous solution. The adsorption behavior of Fe3O4/NMC nanocomposite has been investigated by adsorption kinetics and isotherms adsorption analyses as well. The adsorption isotherm and the adsorption kinetics of Ag(I) onto Fe3O4/NMC agrees well with Langmuir model and pseudo-second-order model, respectively. Moreover, the Fe3O4/NMC was easily to recovery by applied magnetic field, the adsorption capacity of Fe3O4/NMC was about 90.3% of the initial saturation adsorption capacity after five continuous uses.

Abstract A facile soft-template solvent thermal strategy was developed to prepare mesoporous carbon-silica composite (MMCS) by using furfuryl alcohol(FA) as carbon precursor, Pluronic copolymer P123 as template, hydrated iron nitrate as iron source, and teraethylorthosilicate as silicon source and it was applied for the removal of methyl orange (MO). The as-synthesized MMCS with abound of hydrophilic groups processed a high specific surface area, large pore volume, and good magnetic response. With the increase amount of FA, the surface area and functional groups increased, promoting the adsorption effect. The adsorption isotherm, kinetic and thermodynamics were all studied in detail. Additional, it was shown that the adsorption process could not be interfered by the co-existence of PO43-, NO3-, CO32-, SO42- and real water matrix. Thus, the MMCS prepared in this study could be utilized as an alternative adsorbent for the removal of methyl orange from aqueous solution.

New cryogels for selective dye removal from aqueous solution were prepared by free radical polymerization from the highly water-soluble crosslinker N,N,N’,N’-tetramethyl-N,N’-bis(2-ethylmethacrylate)-propyl-1,3-diammonium dibromide and the sulfobetaine monomer 2-(N-3-sulfopropyl-N,N-dimethyl ammonium)ethyl methacrylate. The resulting white and opaque cryogels have micrometer sized pores with a smaller substructure. They adsorb methyl orange (MO) but not methylene blue (MB) from aqueous solution. Mixtures of MO and MB can be separated through selective adsorption of the MO to the cryogels while the MB remains in solution. The resulting cryogels are thus candidates for the removal of hazardous organic substances, as exemplified by MO and MB, from water. Clearly, it is possible that the cryogels are also potentially interesting for removal of other compounds such as pharmaceuticals or pesticides, but this must be investigated further.
