摘要： The present disclosure relates to a method of separating a compound of interest, particularly unsaturated compound(s) of interest, from a mixture. The compound is separated using a column having a chromatographic stationary phase material for various different modes of chromatography containing a first substituent and a second substituent. The first substituent minimizes compound retention variation over time under chromatographic conditions. The second substituent chromatographically and selectively retains the compound by incorporating one or more aromatic, polyaromatic, heterocyclic aromatic, or polyheterocyclic aromatic hydrocarbon groups, each group being optionally substituted with an aliphatic group. In some examples, the present disclosure can include a chromatographic system having a chromatographic column having a stationary phase with a chromatographic substrate containing silica, metal oxide, an inorganic-organic hybrid material, a group of block copolymers, or a combination thereof.

摘要： The present invention relates to a surface modified zeolite adsorbent wherein the surface of said zeolite is modified with a coating comprised of a silicone derived species, said zeolite having a mean crystal size from about 5 to about 10 μm and a skeletal density of ≥1.10 gr./cc. The invention is based on the discovery that larger crystals tend to have higher particle density, and the packing of the larger crystals in agglomeration processes leads to more idealized packing to provide a larger mean-pore diameter. The surface modified adsorbent provides rate selectivity for one gas over others is described. The superior adsorbent has the added convenience of bead forming simultaneously with pore modification as well as having the treatment result in the yielding of high crush strength products.

摘要： A method of removing microplastic particles from a water-based liquid, comprising the exposure of the liquid to a solid surface on which is retained a sorbitan monooleate surfactant, in a concentration suitable for entrapping substantially all microplastic particles. The method is useful for removing microplastic particles and microfibres from fresh and saline natural waters, effluent water, such as grey water, storm water and waste waters from industrial processes, in addition to any kind of product based on water, such as mineral waters, milk, fruit juices, beverages, pharmaceutical and veterinary products.

摘要： The invention relates to a method of producing an activated substrate comprising: •(a) modifying a substrate, wherein the substrate comprises a base matrix, to form a base matrix comprising a leaving group; •(b) contacting the base matrix formed in step (a) with an aminating agent, to thereby provide an aminated base matrix; and •(c) contacting the aminated base matrix formed in step (b) with a heteroaromatic compound, wherein the heteroaromatic compound is a 5 to 12 membered heteroaromatic ring substituted with at least two halogens and optionally one or more further substituents, to produce an activated substrate. The activated substrate maybe contacted with a molecule comprising a ligand specific for a biomolecule to provide a scaffold for isolation of the biomolecule.

摘要： Functionalized filter materials consist of carbons and ceramic substrates for special antimicrobial, phase transfer, and catalytic properties and the method of preparation thereof. The filters are coated with different types of inorganic and polymer impregnates for specific applications in air and water pollution control and catalysis. The substrates are activated by special processes and the impregnates may be reacted with certain redox systems to help increase their efficacy.

摘要： This invention generally relates to a process for manufacturing a lithium selective adsorbent and, more particularly, to a process for manufacturing a lithium selective adsorbent using a recycled and augmented intercalation reaction liquor. An initial quantity of adsorbent precursor is intercalated with lithium using an intercalation reaction liquor to produce an intercalated layered aluminate adsorbent and a post-intercalation reaction liquor. The post-intercalation reaction liquor is decanted, and the intercalated layered aluminate adsorbent is neutralized to produce the lithium selective adsorbent. The decanted intercalation reaction liquor is reconstituted to a pre-intercalation reaction volume of the intercalation reaction liquor, which is recycled to intercalate a subsequent quantity of adsorbent precursor.
