Provided are composite materials that include a polymeric material and one or more metal organic frameworks intermixed with the polymeric material. A polymeric material may be a block copolymer that is optionally polymerized prior to combination with the metal organic framework. The composite materials are useful for many applications including as sorbents for removal of a chemical, optionally a toxic chemical, from a surface where the surface is contracted with the composite material which reacts with or adsorbs the chemical and is then removed to remove the chemical from the surface.

Treatment systems and methods for capable of extracting or extracting and degrading trapped PCBs within a variety of building materials.

According to one embodiment, a treatment solution is provided. The treatment solution is used for treating a byproduct stemming from a process of depositing a silicon-containing material on a member using a gas which includes silicon and halogen. The treatment solution includes at least one of an inorganic base or an organic base and being basic.

According to one embodiment, a treatment solution is provided. The treatment solution is used for treating halosilanes having a cyclic structure. The treatment solution includes at least one of an inorganic base or an organic base and being basic.

Materials for binding per- and polyfluoroalkyl substances (PFAS) are disclosed. A fluidic device comprising the materials for detection and quantification of PFAS in a sample is disclosed. The fluidic device may be configured for multiplexed analyses. Also disclosed are methods for sorbing and remediating PFAS in a sample. The sample may be groundwater containing, or suspected of containing, one or more PFAS.

A reagent set includes an oxidant, acid, and adsorbent, which is used in a method for reducing the leachability and release of PFAS, mercury, and other contaminants from soils, sediments, and other solid materials or waste when treated materials are exposed to acid rain, snow melt, runoff, landfill leachate, etc. The reagents are mixed with a quantity of contaminated material and water is added as needed in order to reduce the leachability of the contaminants from the treated host material, where the admixture end-product suitably removes contaminants from fluids that contact and/or otherwise permeate and/or pass through and/or around the treated admixture. The reagent set and method of use offer environmental professionals long-term, economically viable waste management solutions for removing contaminants from contamination source areas, spill and manufacturing release sites, impacted media, and landfills, as well as from the fluids that contact reagent-treated material.

A treatment method is capable of degrading or sterilizing harmful substances or microorganisms of which the degradation, detoxification, or the like is not easy for ozone gas alone. A harmful substance treatment method is one that makes ozone gas act on harmful substances, microorganisms, or the like in an environment humidified using a surfactant solution. The harmful substances include anticancer drugs. As a surfactant to be used, a non-ionic surfactant, an anionic surfactant, a cationic surfactant, or an amphoteric surfactant can be used.

In one aspect, a composition for decomposing pharmaceutically active agents comprises an oxidizer comprising a permanganate, and an isocyanurate; and an immobilizer. In another aspect, a composition comprises up to 50 wt. % of an oxidizer comprising potassium permanganate and sodium dichloroisocyanurate dehydrate, wherein the wt. % is based on a total weight of the composition.

A method for preparing a biological composition for degrading plant pesticide residues includes: (1) preparing a mixture of a dried coconut shell powder having a water content of less than 3 wt % and a particle diameter of not more than 2 mm and a dried licorice powder having a water content of less than 1 wt % and a particle diameter of not more than 2 mm; (2) hydrolyzing the mixture in a cellulase buffer at pH 4.5 to 5.5 for at least 36 hours, and filtering the mixture to obtain an enzymatic hydrolysate; and (3) adding the enzymatic hydrolysate to a bacteria mixture of yeast and lactic acid bacteria and fermenting at 30 C. to 35 C. for 7-10 days, and centrifuging and lyophilizing to obtain the biological composition.

A CT value controller includes a storage means, an input means, and a computing means. The storage means stores a function expressing a relative humidity and a CT value regarding a degradation degree of an anticancer agent, an assumed relative humidity, and a CT setting. The input means inputs a measured relative humidity and a measured ozone concentration at a time of degradation treatment of the anticancer agent. The computing means calculates a corrected CT value increment based on a difference between the measured relative humidity and the assumed relative humidity at every input of the relative humidity and the ozone concentration by using the function. The computing means determines a termination of the degradation treatment of the anticancer agent when an integrated CT value of the corrected CT value increments reaches the CT setting.
