11648530 · 2023-05-16 · ·

A chiral stationary phase comprises a porous framework material and biomolecules. The porous framework material includes one of the metal-organic framework (MOF) material, the covalent organic framework (COF) material and the hydrogen-bonded organic framework (HOF) material. The biomolecules are biological chiral resolving agents. A pore size of the porous framework material is 0.2-15 nm. The porous framework material serves as a solid carrier. The biomolecules are loaded into the porous framework material. The porous framework material is modified with one or more of carboxyl, hydroxyl, amino, aldehyde, double bonds and mercapto groups.

Bisphenol hypersorbents for enhanced detection of, or protection from, hazardous chemicals

The invention relates to strong hydrogen-bond acidic sorbents. The sorbents may be provided in a form that limits or eliminates intramolecular bonding of the hydrogen-bond acidic site between neighboring sorbent molecules, for example, by providing steric groups adjacent to the hydrogen-bond acidic site. The hydrogen bond site may be a phenolic structure based on a bisphenol architecture. The sorbents of the invention may be used in methods for trapping or detecting hazardous chemicals or explosives.

Method for sulfonating and oxidizing sawdust to form a sorbent

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. A method of using the modified sawdust sorbent for organic dye removal from water is included.
