Abstract: A method for treating an MTBE-contaminated aqueous solution includes forming an adsorbent by treating fly ash with nitric acid and then doping the resultant acid-treated fly ash particles with AgNO3 and calcining. The adsorbent is used to contact an MTBE-contaminated aqueous solution to adsorb the MTBE and the adsorbent and to form a purified aqueous phase which is then separated from the adsorbent.

Abstract: A nanofluid composed of a base fluid and a solid nanocomposite particle, where the solid nanocomposite particle consists of a carbon nanotube and a metal oxide nanoparticle selected from the group consisting of Fe2O3, Al2O3, and CuO. The metal oxide nanoparticle is affixed inside of or to the outer surface of the carbon nanotube, and the solid nanocomposite particle is homogeneously dispersed in the base fluid. The heat transfer and specific heat capacity properties of the nanofluid are measured using differential scanning calorimetry and heat exchanger experiments with different nanocomposite concentrations and different metal oxide percent loadings.

Abstract: Compositions for the adsorptive removal of methyl tertiary butyl ether (MTBE) from contaminated water sources and systems. The compositions contain carbon fly ash doped with silver nanoparticles at specific mass ratios. Methods of preparing and characterizing the adsorbents are described. The composition may contain carbon acid-treated fly ash particles that consist of carbon, oxygen, and sulfur, and have silver oxide nanoparticles present on the surface and in pore spaces of the carbon acid-treated fly ash particles. The composition may be in the form of particles having sizes in a range of 100 nm to 2.5 μm with a BET surface area of at least 16.789 m2/g, and contain the carbon acid-treated fly ash particles and the metal silver oxide nanoparticles at mass percentages of 50-90% and 10-50%, respectively.

Abstract: A process for making an iron oxide impregnated carbon nanotube membrane. In this template-free and binder-free process, iron oxide nanoparticles are homogeneously dispersed onto the surface of carbon nanotubes by wet impregnation. The amount of iron oxide nanoparticles loaded on the carbon nanotubes range from 0.25-80% by weight per total weight of the doped carbon nanotubes. The iron oxide doped carbon nanotubes are then pressed to form a carbon nanotube disc which is then sintered at high temperatures to form a mixed matrix membrane of iron oxide nanoparticles homogeneously dispersed across a carbon nanotube matrix. Methods of characterizing porosity, hydrophilicity and fouling potential of the carbon nanotube membrane are also described.
