STENOTROPHOMONAS MALTOPHILIA GYH AND APPLICATION THEREOF IN DEGRADATION OF CHLORINATED HYDROCARBON POLLUTANTS
The present invention discloses Stenotrophomonas maltophilia GYH and its application in degrading chlorinated hydrocarbon pollutants, and the application is carried out as follows: resting cells obtained by spreading cultivation of Stenotrophomonas maltophilia GYH are added to a pH=5-8 inorganic salt medium, and then a chlorinated hydrocarbon pollutant is added, and the cells are cultured at 20-35° C. and 140-180 rpm to degrade the pollutant. The concentration of chlorinated hydrocarbon pollutant which can be removed by Stenotrophomonas maltophilia GYH ranges from 2.9 mg/L to 8.93 mg/L. Therefore, the Stenotrophomonas maltophilia has a highly efficient degradation ability for similar industrial pollutants and is able to withstand high concentrations of these pollutants.
Method for detoxifying liquid chemical warfare agents using surface-modified metal organic framework
A method of detoxifying a liquid chemical agent is provided using a surface-modified metal organic framework having an amine-based compound deposited on a surface and pores thereof, or bonded to the inside of a frame, wherein when the surface-modified metal organic framework comes into contact with the liquid chemical agent, a reaction with moisture in the atmosphere occurs and, the liquid chemical agent is removed through a hydrolysis reaction, thereby detoxifying chemical agents, such as nerve agents and vesicants, and assuring a high detoxification effect on liquid chemical agents at room temperature even with a small amount of the surface-modified metal organic framework.
FLUIDIC IMPEDANCE PLATFORM FOR IN-SITU DETECTION AND QUANTIFICATION OF PFAS IN GROUNDWATER
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.
MICROBIOLOGICAL CLEANING FORMULATIONS
Microbiological cleaning formulations may include an aqueous solution of a microbial component comprising at least one sporogenous microbial species. The microbiological cleaning formulation may also include a nonionic surfactant. The microbiological cleaning formulations may further include additives, solvents, preservatives, stabilizers, and fragrance agents. The microbiological formulations are such that they may removes organic carcinogens from a surface of a material contaminated during firefighting-related activities or from exposure to organic carcinogens. Corresponding methods for removing organic carcinogens from a surface of a firefighting material may include applying the microbiological cleaning formulation on the surface of the firefighting material. Corresponding cleaning kits may include the microbiological cleaning formulation and an optional scrubbing element.
Activated Carbon Supported Ni0Fe0 Nanoparticles for Reductive Transformation of Perfluoroalkyl-Containing Compounds
The present application relates to a novel method for reductive degradation of perfluoroalkyl-containing compounds, such as perfluoroalkyl sulfonates, by activated carbon (AC) supported zero valent iron-nickle nanoparticles (nNi.sup.0Fe.sup.0).
Controlled medication denaturing composition and method
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.
Compositions and methods for oxidizing and sequestering carbon and stabilizing metals
Compositions and methods for oxidizing organic contaminants while sequestering inhibitory forms of carbon. An oxidant capable of producing free radicals oxidizes organic contaminants. A metal oxide, metal hydroxide, or metal peroxide generates a soluble hydroxide concentration of about 1×10.sup.−4 M or greater to convert carbonic acid, bicarbonate ion, methane, elemental carbon, and other organic forms of carbon to carbonate ion. A metal having a carbonate with a lower solubility product constant than its hydroxide precipitates the carbonate ion as a metal carbonate, thereby eliminating soluble carbonate as a radical scavenger. Compositions and methods that additionally minimize metal solubilization and sequester solubilized metals are also disclosed.
APPARATUS AND METHODS FOR SONOCHEMICAL DEGRADATION OF PER- AND POLYFLUOROALKYL SUBSTANCES
The present disclosure includes systems, devices, and methods for a reactor, such as a sonication reactor, for destruction of Per- and polyfluoroalkyl substances (PFASs). In one aspect of the disclosure, the reactor includes a housing having a base and one or more walls that cooperate to define a chamber and a transducer disposed the chamber. The transducer is configured to generate a plurality of sound waves such that when PFAS solution is disposed within the chamber, the sound waves propagate through the liquid and at least some of the one or more PFAS compounds are pyrolyzed or otherwise degraded. Other aspects and features are also claimed and described.
Activated carbon supported Ni.SUP.0.Fe.SUP.0 .nanoparticles for reductive transformation of perfluoroalkyl-containing compounds
The present application relates to a novel method for reductive degradation of perfluoroalkyl-containing compounds, such as perfluoroalkyl sulfonates, by activated carbon (AC) supported zero valent iron-nickel nanoparticles (nNi.sup.0Fe.sup.0).
