摘要： Emulsified systems of a surfactant-stabilized, biodegradable water-in-solvent emulsion with bimetallic particles contained with the emulsion droplets are useful at removing PCBs from ex situ structures. The hydrophobic emulsion system draws PCBs through the solvent/surfactant membrane. Once inside the membrane, the PCBs diffuse into the bimetallic particles and undergo degradation. The PCBs continue to enter, diffuse, degrade, and biphenyl will exit the particle maintaining a concentration gradient across the membrane and maintaining a driving force of the reaction.

摘要： A process of washing plastics contaminated with polychlorinated biphenyls (PCBs) is provided to reduce the concentration of the PCBs. A two-step process includes a first washing step using a selected washing solution or solvent, such as, a non-flammable solvent, and followed by a second step using thermal desorption. The two-step process enables reducing the concentration of PCBs in polymers, such as recovered from shredder residue, for example, to as low as 0.253 PPM. One of the preferred solvents is Perchloroethylene.

摘要： The subject invention provides a potentially economically viable method for the preparation of hydrogen peroxide (H2O2) in deep eutectic solvents (DES). H2O2 is then used for the destruction of small to large quantities of sulfur and nitrogen mustards and lewisite, their homologous/analogues, and similar chemical warfare agents at ambient conditions in DES without producing any toxic by-products. Furthermore, H2O2 has been used for the destruction of small to large quantities of halogenated hydrocarbons, their homologous/analogues, and similar hazardous chemicals at ambient conditions. H2O2 can be formed by either the electrochemical reduction of oxygen in DES in the presence of water or by dissolving Group 1 (alkali metals) or Group 2 (alkaline earth metals) superoxides, e.g. potassium superoxide, in DES in the presence of water, with/without chemicals used for the enhancement of the solubility of the metal superoxide in the DES, e.g. crown ethers.
