摘要： A cross-linked terpolymer (BSDF) obtained by polycondensation of bisphenol-S, formaldehyde and 1,6-diaminohexane. The terpolymer is highly efficient in eliminating lead ions from aqueous solutions. The adsorption of lead ions on BSDF was studied under different conditions such as: pH, contact time and temperature. The adsorption kinetics fits Lagergren second order kinetic model that are in agreement with the low surface area as a chemisorption process. Applying BSDF on non-spiked and spiked real wastewater samples under optimum conditions revealed the high efficiency of BSDF in removing toxic metal ions.

摘要： Carbon nanofiber doped alumina (Al—CNF) supported MoCo catalysts in hydrodesulfurization (HDS), and/or boron doping, e.g., up to 5 wt % of total catalyst weight, can improve catalytic efficiency. Al—CNF-supported MoCo catalysts, (Al—CNF—MoCo), can reduce the sulfur concentration in fuel, esp. liquid fuel, to below the required limit in a 6 h reaction time. Thus, Al—CNF—MoCo has a higher catalytic activity than Al—MoCo, which may be explained by higher mesoporous surface area and better dispersion of MoCo metals on the AlCNF support relative to alumina support. The BET surface area of Al—MoCo may be 75% less than Al—CNF—MoCo, e.g., 166 vs. 200 m2/g. SEM images indicate that the catalyst nanoparticles can be evenly distributed on the surface of the CNF. The surface area of the AlMoCoB5% may be 206 m2/g, which is higher than AlMoCoB0% and AlMoCoB2%, and AlMoCoB5% has the highest HDS activity, removing more than 98% sulfur and below allowed levels.

摘要： Activated carbon, e.g., from waste tires, modified by bimetallic Fe and Ce nanoparticles can provide high surface area and active sites for enhanced dye adsorption. Such nanocomposites can offer magnetic removal from aqueous solutions containing, e.g., Methylene Blue or Rhodamine B. Adsorption equilibrium data fit well to the Langmuir isotherm model, with an adsorption capacity was 324.6 mg/g. Rhodamine B adsorption by such activated carbon-Fe—Ce magnetic adsorbents has an endothermic character and pseudo-second-order kinetics. In ethanol solution, rhodamine B was desorbed at high efficiency and such materials, which could be recycled up to 5 cycles. Such magnetic nanocomposites are adsorbents for treating dyes such as rhodamine B in wastewater, even in large scale adsorption systems. Polyamides can be grafted to such nanocomposites.

摘要： A composite of polyurethane foam grafted with carbon nanofibers is described. This composite foam may be made by contacting and drying a polyurethane foam with a suspension of carbon nanofibers and then drying. Additional carbon nanofiber layers may be added with repeated contacting. The composite film has a high surface area of 276 m2/g and a hydrophobic character that may be exploited for separating an oil phase from water.

摘要： Cross-linked polymer resins and related salts, solvates, tautomers or stereoisomers are described herein. The cross-linked polymer resins may comprise monomer units of N,N-diallyl aminoalkylphosphonate, a hydrophobic pendant, a tetraallylpiperazinium cross-linker, and sulfur dioxide. A method for producing the cross-linked polymer resins is described. The cross-linked polymer resins may be used as adsorbent materials for the removal of heavy metal ions and contaminant dyes from aqueous solutions. Used cross-linked polymer resins may be removed from solution, cleaned, and reused while maintaining adsorption capacity.

摘要： A cross-linked polymeric resin which contains reacted monomer units of an aniline, a diaminoalkane, and an aldehyde, and which is functionalized with at least one dithiocarbamate moiety. A process for producing the cross-linked polymeric resin whereby an aniline and a diaminoalkane are linked together by Mannich-type polycondensation reactions with an aldehyde. The resulting Mannich-type polycondensation product is converted into the cross-linked polymeric resin through functionalization of one or more amine functional groups with dithiocarbamate moieties. A method for removing heavy metals, such as Hg(II), from an aqueous solution, whereby the cross-linked polymeric resin is contacted with the aqueous solution, and the heavy metal is thus adsorbed onto the cross-linked polymeric resin.
