The present invention relates to a method for preparing an adsorbent for phosphorus adsorption and an adsorbent prepared by the method. More specifically, the present invention is based on the fact that phosphorus has a strong affinity for the surface of metal oxides or hydroxides, and relates to a method for preparing an adsorbent for phosphorus adsorption, which comprises absorbing and coating expanded vermiculite with aluminum and heating the coated vermiculite at high temperature to produce aluminum oxide on the surface of the expanded vermiculite so that the adsorption of phosphorus at the coordination of the oxide can be achieved with very high efficiency by a strong attraction between phosphorus ions and aluminum ions, and to an adsorbent prepared by the method.

A method for manufacturing a granular excretion disposal material having a core portion and a covering layer that covers the core portion. The method includes: a granulating step of granulating the core portion by blending a core portion raw material containing pulp and highly absorbent resin, with water; a covering step of forming the covering layer by spraying a covering layer raw material containing pulp and highly absorbent resin, onto a surface of the core portion granulated in the granulating step; a drying step of drying a granular matter, in which the covering layer is formed in the covering step, with hot air; and a cooling step of cooling the granular matter dried in the drying step.

An adsorption device for compressed gas or a non-compressed gas, is provided with a vessel with an inlet for the supply of a compressed gas or a non-compressed gas to be treated, and an outlet for treated gas and an adsorption element is affixed in the vessel. The adsorption element extends along the flow direction of the compressed gas or the non-compressed gas to be treated, between the inlet and the outlet. The adsorption element has a monolithic supporting structure that is at least partially provided with a coating that contains an adsorbent.

Provided herein is a chromatography media composed of a porous solid substrate (such as a membrane, metal, or metallic alloy) that is coated with hydroxyapatite (IA). Also provided is a chromatography media comprising a HA-coated substrate and uses thereof. Thus this disclosure provides a chromatography media composed of a porous solid substrate (such as a membrane, metal, or metallic alloy) that is coated with I-IA. Also provided is a chromatography media comprising a HA-coated substrate and uses thereof. Methods of preparing the HA-coated substrate are also provided.

Articles are provided for absorbing fluids. In embodiments, the articles of the present disclosure are modified to make them hydrophobic, thereby decreasing their affinity for water and similar liquids, while increasing their affinity for other hydrophobic materials, including oil. After use, the articles, in embodiments polyurethane sponges, may have their absorbed materials removed therefrom, and the articles may then be reused to absorb additional materials.
