A method of mitigating the environmental impact of invasive fish in rivers and lakes is provided. The method comprising recruiting overfishing of a species of fish harvested from one or more rivers or lakes in which the species of fish is invasive, obtaining fish bones from the harvested fish, producing a sorbent from the fish bones by drying and milling the fish bones into sorbent particles having a metal sorption capacity effective for treating a metal contaminated material, and treating metal contaminated material with an effective amount of the sorbent to form immobilized reaction products of the metal contaminated material and the sorbent.

Amine-functionalized organosilica materials are provided that have improved stability when exposed to oxidizing/oxygen-containing environments during cycling of temperature, such as the cycling of temperature that occurs when using a material as a sorbent during successive adsorption/desorption cycles. Methods of performing CO.sub.2 sorption/desorption with improved stability of the organosilica sorbent material are also provided. The improved stability is achieved in part by using amine-functionalized organosilica materials where the amine-functionalization is provided by functional groups that include primary amines but do not include secondary amines. Still further improvements in stability can be achieved when the functionalization is provided by a functional group that includes a primary amine while also not having any hydrogens on a carbon atom that is in the beta position relative to the primary amine.

A system and method for 3D printed polymeric ionic liquid (PIL) extraction sorbents that includes a photocuring 3D printer utilizing a buildplate having a plurality of holes and a resin tank formed of a plurality of individual wells with a prepolymer monomer blended with a crosslinker and a photoinitiator is placed in the plurality of wells to form a plurality of 3D printed PIL sorbents on the buildplate, a fabrication device that prepares the polymeric ionic liquid (PIL) for extraction, at least one container for conditioning, extracting, and desorption of the polymeric ionic liquid (PIL); and a high-performance liquid chromatography (HPLC) to provide separation resulting in batch production of PIL sorbents. A polymeric ionic liquid (PIL) sorbent printed by 3D printer includes at least one PIL sorbent and can be in the form of a blade or fiber that has a high level of consistency.

Systems and methods for an atmospheric carbon dioxide removal system are disclosed herein. The system may include a carbon capture vessel including two or more intermodal containers connected end to end and sealed to define a first hollow interior and configured to receive an air flow. Sorbent material subcontainers may be disposed within the first hollow interior of the connected intermodal containers and may include a outer sidewall defining a second hollow interior. A sorbent material may be disposed around an exterior of the outer sidewall of each subcontainer. The carbon capture vessel may also include a plate to prevent air from entering/exiting the first hollow interior a fan to direct the air flow into the subcontainers, pipes to direct fluid flow inside/outside the subcontainers, and at least one door, gate, or flap valve to prevent the fluid flow from exiting a first end of the connected intermodal containers.

A TPC-OTBS n-hexane solution is added to a mixture of TPC-OSO.sub.2F, DMF, and DBU and allowed to stand to produce a crosslinked solvent gel; the crosslinked solvent gel is added to methanol, stirred, and dried to produce the porous crosslinked material. The gel acquired can be prepared into a pore-rich solid porous organic polymer material by means of solvent exchange. SEM and TEM are used to characterize the surface and internal morphologies of the solid material, and the porous morphology thereof is discovered, with large pores being the majority. Infrared and nuclear magnetic resonance are used to characterize the structure of a crosslinked polysulfate; the complete reaction of a sulfuryl fluoride group is proven by means of solid-state fluorine nuclear magnetic resonance spectroscopy and XPS element analysis; and the porous structure of the crosslinked polysulfate allows same to be provided with improved application prospect in terms of adsorption.

The method includes mixing an aldehyde and a first solvent to form a mixture. The method further includes mixing an organosulfur phenol and an aromatic compound to the mixture to form a phenol mixture and heating the phenol mixture in the presence of an acid to form a solid. The solid is dried to obtain the cross-linked porous polymer. The obtained cross-linked porous polymer has repeat pyrrole units bonded to one another, and the cross-linked porous polymer has a thiol group which separates non-adjacent pyrrole units. The cross-linked porous polymer obtained after drying is in a form of solid particles having a spherical particle structure.

High purity carbon sorbent monoliths, particularly effective for the removal of trace-contaminants such as ammonia, formaldehyde, and methyl mercaptan from a gas flow, are fabricated by 3D-printing polymer monoliths, pre-oxidizing them in a flow of air at a temperature below the melting point of the polymer precursor, carbonizing them, and subsequently activating them to a weight loss of about 20 percent. The pre-oxidation step effectively prevents polymer-monolith swelling and melting during carbonization.

The present disclosure provides a preparation method of a porous hydrogel adsorbent based on Radix astragali residues, including the following steps: subjecting residues of Chinese herbal medicine Radix astragali as a precursor to bleaching with NaClO.sub.2, alkaline washing with KOH, and high power ultrasonic treatment, thereby obtaining a precursor solution of uniformly dispersed cellulose nanofibers (CNFs); adding the precursor solution of CNFs to a mixed solution of N,N-methylene bisacrylamide (MBA), acrylic acid (AA) and ammonium persulfate (APS), shaking evenly, and initiating a polymerization reaction at a predetermined temperature to form a monolithic gel; and cleaning the monolithic gel, putting the cleaned monolithic gel into a dimethyl sulfoxide (DMSO) solution containing epichlorohydrin to allow reaction, and transferring the product of the reaction to an aqueous sodium hydroxide solution containing triethylene tetramine to allow reaction, thereby finally obtaining an amino-functionalized porous hydrogel adsorbent.
