The invention relates to a textile protective material, in particular providing protection against radioactive harmful and/or toxic substances and/or against biological harmful and/or toxic substances and/or against chemical harmful and/or toxic substances, preferably a textile adsorption filter material, and to a method for the production thereof. The textile protective material is suitable in particular for producing protective equipment and protective objects and filters and filter materials of all types.

The present invention provides processes for filtering undesired chemicals in streams of contaminated air for supply to confined areas. The processes provide (1) contacting air with a filter comprising by volume from about 5% to about 95% impregnated zirconium hydroxide, from about 5% to about 95% activated impregnated carbon, and optionally, up to about 50% ammonia removal material; and (2) supplying the contacted air to a confined area.

The nanoparticle purifying system includes a container having an interior portion including a plurality of aluminum plates. Each of the plurality of aluminum plates includes a solid filtering agent, such as activated charcoal and, optionally, sodium tetra borate. The container can further include an inlet for receiving polluted air, an outlet for discharging purified air, and a pathway extending between the plurality of aluminum plates from the inlet to the outlet. The nanoparticle purifying system includes a removable lid for disposing on the container. Each of the plurality of aluminum plates can include an adhesive, such as hot glue and/or carpet glue, for attaching the solid filtering agent to the surfaces of the plurality of aluminum plates and interior surfaces of the container.

A method and composition of matter for detecting and decontaminating hazardous chemicals, the composition of matter including: a magnetic material for any of chemisorbing, molecularly dissociating, or decomposing a hazardous chemical, wherein the magnetic material changes its magnetic moment upon any of chemisorption, decomposition, and molecular dissociation of the hazardous chemical and the change in magnetic moment is used to detect the presence of the hazardous chemical, and wherein the hazardous chemical includes any of toxic industrial chemicals, chemical warfare agents, and chemical warfare agent related compounds.

Provided are processes of removing or sequestering a basic or an acid gas from a sample by contacting the sample with a filtration media that includes a porous zirconium hydroxide impregnated with a transition metal reactant. The resulting filtration media has the ability to remove or sequester both acid and basic gases, is stable, and highly functional so as to be useful in protective equipment or other filtration systems.

A process for the rapid fabrication of a sorbent hollow fiber membrane (HFM) with a very high metal organic framework (MOF) content as well as the apparatus to contain such fibers for the purposes of sequestering and separating chemicals is described. Herein we developed a process to rapidly prototype meters long HFM batches with a high MOF content for sequestering and filtration. The HFM produced herein can be tailored to precisely sequester chemical of a hazardous nature which may include chemical warfare agents (CWA) or toxic industrial chemicals (TIC). The HFM are comprised of a polymer-based material that includes a polymeric binder; and one or more porous active materials that adsorb, chemisorb, decompose, or a combination thereof, a hazardous chemical.

Systems and methods for removal of gas phase contaminants may utilize catalytic oxidation. For example, a method may include passing a gas that includes a gas phase contaminant through a catalytic membrane reactor at a temperature of about 150 C. to about 300 C., wherein the catalytic membrane reactor includes a bundle of tubular inorganic membranes, wherein each of the tubular inorganic membranes comprise a macroporous tubular substrate with an oxidative catalyst and a microporous layer disposed on a bore side of the macroporous tubular substrate, and wherein at least about 50% of the gas flows through the tubular inorganic membranes in a Knudsen flow regime; and oxidizing at least some of the gas phase contaminant with the oxidative catalyst layer, thereby reducing a concentration of the gas phase contaminant in the gas.
