The present disclosure relates, according to some embodiments, to a method for recovery of lithium ions from a lithium-ion containing liquid, the method comprising the steps of coating a nanoparticle with a styrene monomer; polymerizing the styrene monomer to form a poly-styrene-coated nanoparticle; attaching a dibenzo-12-crown-4-ether to the polystyrene-coated nanoparticle to form a lithium adsorbing medium; exposing the lithium ion-containing liquid to the lithium adsorbing medium to form a lithium-rich adsorbing medium; and extracting the lithium ion from the lithium-rich adsorbing medium.

A dual ligand sol-gel sorbent and method of manufacture is provided herein. The dual ligand sol-gel sorbent provides superior enrichment effects through simultaneous exploitation of superhydrophobicity of one of the ligands and the ability of the other ligand to undergo - interaction with hydrophobic aromatic analytes. Sorbent performance is enhanced both in terms of analyte enrichment and sorbent stability, such as pH stability and solvent stability.

An example coating configured to be applied to a basic gas filter substrate includes a water-soluble polymer and an organic phosphate or phosphonate reactant. An example technique includes applying a coating to a substrate and heating at least the coating to a temperature between about 100 C. and about 275 C. for about 1 minute to about 10 minutes. An example system includes a basic gas filter including a coating, and a sensor configured to sense an optical change in the coating.

Chromatography resins having mixed mode ligands and methods of using such resins are provided.

Magnetic and non-magnetic microparticle binding surfaces for the simple, cost-effective and automatable depletion of sample interferences within the assay blocking threshold and enrichment of biomarkers are provided, as are methods and compositions for their preparation and use. The binding surfaces may comprise non-magnetic, magnetic, paramagnetic, and superparamagnetic microparticles, or combinations thereof. The methods include methods for making microparticulate binding surfaces that consist of binders, binding partners, capture moieties, or combinations thereof for multi-functional sample depletion and enrichment.

The deodorizing material of the present invention comprises fibrous activated carbon; and (A) an aromatic amine and a sulfate of the aromatic amine or (B) an aromatic amine, a sulfate of the aromatic amine, and sulfuric acid, supported on the fibrous activated carbon, wherein a total substance amount of the aromatic amine and the sulfate of the aromatic amine supported per gram of the fibrous activated carbon is 0.85 to 1.35 mmol, and a ratio of the total substance amount (mmol) of the aromatic amine and the sulfate of the aromatic amine supported per gram of the fibrous activated carbon relative to a total substance amount (mmol) of the sulfate of the aromatic amine and the sulfuric acid supported per gram of the fibrous activated carbon ([total substance amount of the aromatic amine and the sulfate of the aromatic amine][total substance amount of the sulfate of the aromatic amine and the sulfuric acid]) is 5.0 to 7.5.

A method for producing a modified sawdust sorbent. The method involves sulfonating sawdust with sulfuric acid and oxidizing the sulfonated sawdust with hydrogen peroxide. The method yields a modified sawdust sorbent containing sulfonated and oxidized cellulose. The modified sawdust sorbent has a higher surface area, higher organic dye adsorption capacity, and more rapid organic dye adsorption rate than unmodified sawdust. Also disclosed is a method of using the modified sawdust sorbent for organic dye removal from water.

Disclosed in certain embodiments are carbon dioxide sorbents that include porous particles impregnated with an amine compound.

The present invention relates generally to compositions for use in biological and chemical separations, as well as other applications. More specifically, the present invention relates to hybrid felts fabricated from electrospun nanofibers with high permeance and high capacity. Such hybrid felts utilize derivatized cellulose, and at least one non-cellulose-based polymer that may be removed from the felt by subjecting it to moderately elevated temperatures and/or solvents capable of dissolving the non-cellulose-based polymer to leave behind a porous nanofiber felt having more uniform pore sizes and other enhanced properties when compared to single component nanofiber felts.
