Adsorbent particles each containing: a carrier particle containing an organic polymer containing a monomer unit derived from a styrene-based monomer; a hydrophilic organic compound adhered to a surface of the carrier particle; and a diglycolic acid residue bonded to the hydrophilic organic compound. When a BET specific surface of the adsorbent particles as determined by adsorption of nitrogen gas is X.sub.0 and a BET specific surface area of the adsorbent particles as determined by adsorption of water vapor is X.sub.1, X.sub.1/X.sub.0 is 0.10 to 1.0.

A filter medium is provided with a layer (A) provided with non-impregnated active carbon, a layer (B) with a solid carrier material that is impregnated with a permanganate salt, and a layer (C) with alkaline impregnated active carbon. The layer (B) and the layer (C) are arranged such that a gas flowing through the filter medium flows through the layer (B) before flowing through the layer (C). The layer (A) is arranged such that the gas flowing through the filter medium flows through the layer (A) before flowing through the layer (B) or the gas flowing through the filter medium flows through the layer (A) after flowing through the layer (C).

A method of extracting an analyte from a sample is described where the sample includes water. The sample and polymeric drying agent are added to a container. The polymeric drying agent includes a cationic monomer, an anionic monomer, and a crosslinker. The polymeric drying agent is configured to sorb water from the sample.

A method of absorbing falling precipitation to prevent the falling precipitation from reaching an area for an activity includes spreading a sufficient amount of a water absorbent including superabsorbent granules over the area prior to or during the falling precipitation so that the superabsorbent granules can absorb the water before the falling precipitation can reach the area wherein the activity can immediately occur after the falling precipitation stops and the water absorbent is removed. Another method of absorbing falling precipitation to prevent the falling precipitation from reaching an area for an activity includes placing an application bag over the area prior to or during the falling precipitation, wherein the application bag includes a sufficient amount of superabsorbent granules inside a casing, wherein the superabsorbent granules can absorb the falling precipitation before the falling precipitation can reach the area, and wherein the activity can immediately occur after the falling precipitation stops and the application bag is removed.

Provided herein are materials and methods of reducing contamination in a biological substance or treating contamination in a subject by one or more toxins comprising contacting the biological substance with an effective amount of a sorbent capable of sorbing the toxin, wherein the sorbent comprises a plurality of pores ranging from 50 Å to 40,000 Å with a pore volume of 0.5 cc/g to 5.0 cc/g and a size of 0.05 mm to 2 cm and sorbing the toxin. Also provided are kits to reduce contamination by one or more toxins in a biological substance comprising a sorbent capable of sorbing a toxin, wherein the sorbent comprises a plurality of pores ranging from 50 Å to 40,000 Å with a pore volume of 0.5 cc/g to 5.0 cc/g and a size of 0.05 mm to 2 cm and a vessel to store said sorbent when not in use together with packaging for same.

The present invention relates to a fully moisture-tight multilayer material, which is also able to absorb, retain and not release the absorbed moisture or free water into the formulations containing pharmacological active substances and/or instable components with biological activity and/or effervescent and/or easily perishable formulations; said material being useful for preparing bags, envelopes and sachets for packaging food, dietary and cosmetic products, medical devices and medicinal products. The multilayer material of the present invention is a multilayer material that is useful for preparing containers in the form of bags, envelopes, sachets and sticks coming into direct contact with the formulations of the food, dietary and cosmetic products as well as of the medical devices and medicinal products in the form of e.g. lactic bacteria and/or bifidobacteria in powders or granules, either dried or freeze-dried.

A BAK removal device is constructed as a plug of microparticles of a hydrophilic polymeric gel that displays a hydraulic permeability greater than 0.01 Da. The polymer hydrophilic polymeric gel comprises poly(2-hydroxyethyl methacrylate) (pHEMA). The particles are 2 to 100 μm and the plug has a surface area of 30 mm.sup.2 to 2 mm.sup.2 and a length of 2 mm to 25 mm and wherein the microparticles of a hydrophilic polymeric gel has a pore radius of 3 to 60 μm.

A method of preparing absorbent polymer granules is provided. The method of preparing fine particle granules according to the present disclosure may provide granules of which re-breaking is minimized due to a superior binding force between fine particles.

An apparatus for collection and disposal of fats, oil and grease that includes a fabric container having at least one open end, a biogradable material capable of absorbing a large quantity of fats, oil and grease positioned in the container through the open end, the container and biogradable material adapted for being placed in a source of fats, oil and/or grease for absorbing the fats, oil and/or grease for removal from the source and for transport to a location for processing.

Porous polymeric resins, reaction mixtures and methods that can be used to prepare the porous polymeric resins, and uses of the porous polymeric resin are described. More specifically, the polymeric resins typically have a hierarchical porous structure plus reactive groups that can be used to interact with or react with a variety of different target compounds. The reactive groups can be selected from an acidic group or a salt thereof, an amino group or salt thereof, a hydroxyl group, an azlactone group, a glycidyl group, or a combination thereof.
