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.

An absorbent article comprising an absorbent gelling material (AGM) having an encapsulated compound of one or more odor controlling organic compounds disposed upon a surface thereof is described. Alternatively, an AGM particle comprising an encapsulated reactive compound of one or more odor controlling organic compounds disposed as a surface coating thereon is described. Additionally, a method to manufacture an absorbent article is described. The method provides for the steps of: a) providing a solution in a solvent system, the solution has an encapsulating agent and one or more odor controlling organic compounds as a surface coating; b) applying an amount of the solution to a surface of an AGM particle; and, c) incorporating the AGM particle having the solution applied thereto into the absorbent article.

An antimicrobial filter media, which includes a non-woven fabric; and an antimicrobial agent bound to the nonwoven fabric by a binder, the antimicrobial agent including silver sodium zirconium hydrogenphosphate and thiabendazole, and the silver sodium zirconium hydrogenphosphate and the thiabendazole are employed at a weight ratio of 1:1.5 to 1.5:1, to an air cleaner including the same, and to a process for preparing the same. The antimicrobial filter media includes silver sodium zirconium hydrogenphosphate and thiabendazole, as an antimicrobial agent, at a specific weight ratio. As a result, it is possible to effectively filter harmful microorganisms to supply purified air, to have excellent antibacterial, antiviral, and antifungal properties at the same time, and to further enhance the durability and lifespan characteristics by virtue of excellent filter damage prevention effect.

A method for producing modified sawdust sorbent that includes sulfonating sawdust with sulfuric acid and oxidizing the sulfonated sawdust with hydrogen peroxide. The method yields 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 includes contacting dye contaminated water with the modified sawdust sorbent and forming a dye-impregnated sorbent and decontaminated water.

The present invention relates to a carbon dioxide adsorbent based on a hydrophobic silane-coated amine-functionalized MOF/alumina composite and, more specifically, to a carbon dioxide adsorbent based on a hydrophobic silane-coated amine-functionalized MOF/alumina composite, capable of maintaining structural stability by means of the moisture present in exhaust gas, and thus can effectively capture carbon dioxide in a real fluidized bed. According to the present invention, provided are a carbon dioxide adsorbent and a preparation method therefor, the carbon dioxide adsorbent being capable of maintaining structural stability by means of the moisture present in exhaust gas since the surface of a porous metal-organic framework/alumina oxide composite is coated with hydrophobic silane.

This disclosure relates to new filtration systems, granular substrates, granular media and processes that are highly effective for removing suspended oil, particulates and oily particulates from an oil-water mixture. The new filtration media comprises a microporous granular substrate having a combination of specified micro-porosity, hardness and additional characteristics, the substrate being modified by an infused or coated absorption composition. This resulting filtration media displays excellent filtration performance, including outstanding durability and robustness to sustain its excellent performance over a large number of backwash cycles.
