Method of depleting an organosilicon component in a mixture using a sorbent copolymer and apparatus for practicing the method
A method and apparatus for removing an organosilicon component from a mixture are disclosed. The method and apparatus employ a copolymer of a di-alkenyl functional aromatic hydrocarbon and a polyorganosiloxane as the sorbent.
Magnetic, superhydrophobic and superoleophilic medium, synthesizing methods and applications of same
A medium for fast, selective oil-water separation and/or oil absorption includes steel wool modified with a polymer a polymer or a polymer mixture. The polymer or the polymer mixture is adapted such that the medium is a superwetting material that is superhydrophobic and superoleophilic under water. The polymer or the polymer mixture includes polydimethylsiloxane, polytetrafluoroethylene, polyvinylpyrrolidone, or a combination thereof. The solution immersion method used to synthesize the medium requires only a single, simple step and affordable materials and, as a result, is easy to scale up.
IMPROVEMENTS RELATING TO WATER PURIFICATION
A method of obtaining water from a liquid composition comprising water, the method comprising: (a) providing a sorbent material; (b) contacting the sorbent material with the liquid composition comprising water; (c) separating the sorbent material and the liquid composition comprising water; and (d) desorbing water from the sorbent material; wherein the sorbent material is a metal-organic material.
POLYAMINE PHOSPHORUS DENDRIMER MATERIALS FOR METAL SEQUESTRATION
The present disclosure provides novel solid sorbents synthesized by the reaction of polyamines with polyaldehyde phosphorus dendrimer (P-dendrimer) compounds for metal sequestration. The sorbents are highly stable and exhibit desirable thermodynamics and reaction kinetics with a wide variety of metals including heavy metals and rare earth elements. The sorbents can be easily regenerated for repeated use to extract metals from an aqueous solution. The materials are stable to aqueous and organic media, as well as strong acid and bases. The sorbents maintain full capacity over many cycles of use.
SILOXANE REMOVAL SYSTEMS AND METHODS
Systems for and methods of treating a fluid containing siloxanes, silanes and/or other silicon compounds. A hot box is configured to receive an initial flow of the fluid, react the flow with water at a temperature and pressure suitable for hydrolysis to generate a first treated flow, in which at least a portion is hydrolyzed to produce silicon dioxide and methane, and discharge the first treated flow. A solid removal mechanism can be configured to receive the first treated flow, separate at least a portion of the silicon dioxide as solid material, and discharge the remaining components as a second treated flow. Techniques of the present disclosure can lead to very low siloxane levels.
Asymmetric electrochemical systems and methods
An asymmetric system containing a first conductive polymer modified with a redox active moiety and a second conductive polymer modified with a surfactant is used for the separation of organic compounds from aqueous solutions. The asymmetric system has complementary hydrophobicity tunability in response to electrochemical modulations. For example, both materials are hydrophobic in their respective neutral states, therefore exhibiting affinity toward organic compounds. Application of a mild potential drives the desorption of the organic compounds and regeneration of the materials. The asymmetric system can be used in a cyclic fashion, through repeated electrical discharge or shorting of the two electrodes to program the capture of organics from a feed solution, and application of a potential to stimulate the release of the adsorbed organics.
TREATMENT AND REGENERATION SYSTEM AND METHOD FOR EXTRACTING ORGANIC SOLUTES FROM-WATER
Provided is a system and method for extracting organic solutes from water with a filter media. The system and method allow for regenerating the filter media following treatment of a water supply containing one or more organic solutes to allow the media to be reused for subsequent water treatment operations. The system and method also allows for regeneration of the displacement fluid for reuse in the regeneration of the media with recovery of at least one or more organic solutes from the displacement fluid. Additionally, the system and method allows for substantially continuous treatment of a water supply and regeneration of a filter media.
NANONETS FOR REMOVAL OF CONTAMINANTS FROM AQUEOUS SOLUTIONS, KITS THEREFOR AND METHODS OF THEIR USE
