An improved flow rate metering device that provides for the mixing and dispensing of two or more fluids to form final mixture, for example, for automatic washing of cars and trucks. More specifically, the invention is a system that mixes and ejects chemicals, creating a very precise mixture of one or more chemicals with a dilutant, such as water. The device also has the capability of monitoring an entire chemical dilution and release system, comprising multiple chemicals, and using software to document past and current usage rates, along with predicting future usage rates based upon both past usage rates and environmental conditions.

Methods for disposing of munition components may include separating propellants from heavy metal penetrators and disposing of those separated components into different types of geological formations. The initially solid form propellants may be converted into a stable liquified propellant form, by a particular disclosed process, that may be injected within salt water (injection) disposal wells, where distal portions of such salt water disposal wells may be located in a geological formation of substantially at least one salt. The separated heavy metal penetrators (with or without their associated projectile jackets) may be disposed of within human-made caverns, where such human-made caverns may be located within a deep geological formation that is often 2,000 feet or more below the Earth's surface. The heavy metal penetrators may include uranium (depleted uranium). Portions of a given munition, to be disposed of, may be radioactive.

The present invention is directed towards a composition for decontaminating surfaces contaminated with toxic chemicals/substances, comprising at least one type of metal oxyhydroxide such as zirconium hydroxide, Zr(OH).sub.4, optionally with added water for hydration of the solid, mixed into a carrier liquid used for application to a contaminated surface.

Metal ion-directed carboxylic acid functionalized polyoxometalate hybrid compounds, and their preparation method and applications in catalyzing the degradation of chemical warfare agent simulants. In the synthesis, Na.sub.2MoO.sub.4, p-hydroxybenzonic acid (PHBA), alanine (Ala), KCl, transition metal cations and As.sub.2O.sub.3 as raw materials and water are used as solvent. At room temperature, 2-chloroethyl ethyl sulfide (CEES) and the prepared polyoxometalate hybrid compounds were mixed together in anhydrous ethanol and stirred, and H.sub.2O.sub.2 was subsequently added into the reaction system. The catalytic reaction for the degradation of CEES was finished within 5 min under stirring. In the catalytic hydrolysis of diethyl cyanophosphonate (DECP), the catalyst, DECP, DMF and H.sub.2O were put together and mixed fully. The prepared polyoxometalate hybrid compounds have the advantages of high conversion, high selectivity and easy recyclability in catalyzing the degradation of two types of chemical warfare agent simulant.

Disclosed herein are methods and systems for treating a waste substance containing perfluoro- and polyfluoroalkyl substances (PFAS). The method includes combining the PFAS with a first amendment in a reactor to create a combination, heating and pressurizing the combination to hydrothermal conditions, and holding the combination at hydrothermal conditions for a holding time sufficient to at least partially mineralize the PFAS to create a treated combination.

The present invention relates to a method of detoxifying a liquid chemical agent using a metal organic framework having a surface modified with a basic amine-based compound. More particularly, a surface-modified metal organic framework having the amine-based compound deposited on a surface thereof and in pores thereof or bonded to the inside of a frame is prepared, and when the surface-modified metal organic framework comes into contact with the liquid chemical agent, a reaction with moisture in the atmosphere occurs, thus removing the liquid chemical agent through a hydrolysis reaction. It is possible to simultaneously detoxify various chemical agents such as a nerve agent and a vesicant, thus assuring a high detoxification effect on liquid chemical agents at room temperature even when using a small amount thereof.
