摘要:
This disclosure relates generally to methods and rare earth-containing additives for removing target materials in the form of hydroxides, carbonates, hydrates, or oxyhydroxyls from, a typically aqueous, liquid medium.
摘要:
A new device, method, and system are disclosed that provide for removal of undesired materials from a contaminated fluid. Materials present in the fluids are kept in motion in one or more filter cassettes that include disc aerators that improve contact times with the sorbents and that rotate the filter media to pump contaminated water through the filter media for treatment of the contaminated fluids. The device and system provide containment of sorbent fines that keeps the filter media free from clogging.

摘要:
A porous structured organic film for storing gaseous a gaseous entity and method for storing gaseous entities in a porous structured organic film, the porous structured organic film including a plurality of segments and a plurality of linkers arranged as a covalent organic framework, wherein at a macroscopic level the covalent organic framework is a film and contains a plurality of sites accessible to one or more gaseous entity.
摘要:
A clean, high efficiency, low pressure drop, adsorptive filter material that is porous and includes an acidic functional group. The filter can include, for example, a non-woven filter composite has a porous sulfonated divinyl benzene styrene copolymer beads having sulfonic acid functional side groups. The non-woven filter is used to remove molecular bases, including ammonia, organic amines, inides, aminoalcohols, alcoholoamines from the atmosphere used in semiconductor fabrication and other processes that require uncontaminated gaseous environments of high quality.
摘要:
Carriers coated with a copolymer of a hydrophilic acrylate or methacrylate monomer and a copolymerizable unsaturated carboxylic acid or unsaturated amine are provided which are substantially free from nonspecific adsorption of proteins and the like. Due to the side-chain carboxyl or amino groups of the copolymer, these coated carriers are able to immobilize bio-active materials such as antigens, antibodies, complements and enzymes. These carriers, on which bio-active materials can be immobilized, are useful as clinical selective adsorbents, affinity-chromatographic adsorbents, selective electrodes or columns for analysis.
摘要:
A water filtration apparatus and a method of using thereof, wherein the water filtration apparatus includes a nanoparticle layer which comprises polypeptide-functionalized nanoparticles that are capable of absorbing heavy metals selected from the group consisting of Pb2+, As5+, Cd2+, Hg2+, Cr6+, Cu2+, and Zn2+, as well as organic materials. Various embodiments of the water filtration apparatus, the method of using the apparatus, and a method of producing the polypeptide-functionalized nanoparticles are also provided.
摘要:
A water absorbing material contains paper powder obtained by separating gypsum from a gypsum board as its raw material. The weight ratio of the gypsum adhering to the paper powder with respect to the paper powder is 5% or less.
摘要:
A non-woven body for binding mercury, comprising a substrate made from a nonwoven fabric, wherein the body is doped with gold on the outside and with silver on the inside, is characterized in that the substrate comprises an outer ply that encloses the outside, an inner play that encloses the inside, and an electrically neutral intermediate ply is interposed between the outer ply and the inner ply. Such a non-woven body may be used as a protective mask of also as lining for a box for disposal of broken energy-saving lamps.
