A process for gas-phase synthesis of titanium dioxide aerosol gels with controlled monomer size and crystalline phase using a diffusion flame aerosol reactor operated in a buoyancy-opposed configuration is disclosed. The process includes introducing a precursor stream into a diffusion flame aerosol reactor, introducing a fuel stream into the reactor, combusting the precursor stream and the fuel stream in a flame to form at least one nanoparticle, and operating the reactor in a down-fired buoyancy-opposed configuration to produce the aerosol gel.

Disclosed herein are extraction chromatographic supports comprising a porous support, an inert filler, and metal ion binding extractant that may be used for chromatographic separation of metal ions. Also disclosed herein are methods for preparing and using the extraction chromatographic supports.

The present invention discloses a lignin-based hierarchical porous carbon with high specific surface area and preparation method and application thereof. The present invention employs maleic anhydride, acrylic acid, and hypophosphorous acid to modify a lignin, then performs a cross-linking reaction with a glutaraldehyde-triethanolamine condensate to prepare a lignin graft-copolymerized by phosphino carboxylic acid copolymer, and then dropwise adding a soluble calcium salt solution and a soluble carbonate solution into the lignin graft-copolymerized by phosphino carboxylic acid copolymer dispersion successively, co-precipitates to prepare a lignin/nano CaCO.sub.3 complex, finally obtains a lignin-based hierarchical porous carbon with high specific surface area through carbonizing at a high temperature. The preparation method of the present invention may enable nano CaCO.sub.3 to be uniformly and stably dispersed in a three-dimensional network structure of the lignin graft-copolymerized by phosphino carboxylic acid copolymer, realizing full and uniform complexation of the lignin with nano CaCO.sub.3.

A method of treating wood chips to be used as a media for ameliorating oil spills on land or water involves heating in a mixture of petroleum wax and vegetable oil to remove moisture content and open the pores of the wood chip to allow the oil/wax blend to penetrate into the interior of the wood chips and subsequently grinding up the chips to a predetermined mesh size. The ground chips impregnated with wax/oil are then blended with magnetic iron ore concentrate and packaged/bagged for later distribution on an oil slick. The magnetic iron ore concentrate clings to the ground, oil/wax coated wood chips and facilitates retrieving the ground chips that have absorbed the spilled oil using a magnetic pick-up.

The present disclosure relates to compositions including metal-organic framework materials and a polymeric binder. The compositions may have a crush strength of about 2.5 lb-force or greater. The present disclosure also relates to processes for producing metal-organic framework extrudates. Processes may include mixing a metal-organic framework material, a polymeric binder, and optionally a solvent to form a mixture. The process may also include extruding the mixture to form a metal-organic framework extrudate.

This invention relates to a process for treating acid mine drainage (AMD). The process includes the steps of adjusting the pH of the AMD to be in the range of 3 to 5; adding maghemite nanoparticles to form a slurry; and a) aerating the slurry obtained in step 3), or b) simultaneously heating and mixing the slurry obtained in step 3). Thereafter maghemite nanoparticles loaded with one or more metals and sulphate and precipitated metals is separated from the slurry.
