摘要:
One object of the present invention is to produce a weakly acidic cation exchanger under mild conditions. Another object of the present invention is to produce a more firm weakly acidic cation exchange film. Still another object of the present invention is to provide a weakly acidic cation exchanger capable of realizing high-level separation of monovalent cation and simultaneously analyzing monovalent cation and divalent cation and also provide a chromatography column using the ion exchanger. In the production method of a weakly acidic cation exchanger of the invention, a solvent incapable of dissolving a polymer having a double bond within the molecule is used and the weakly acidic cation exchanger is produced by polymerization at temperature of 100° C. or less.
摘要:
A fabric phase sorptive extractor (FPSE) is a sampling device where a flexible fabric is coated with at least one sol-gel derived film that includes at least two of a metal oxide portion, a siloxy portion, and an organic portion, where the gel has at least some amorphous portions. The FPSE is flexible such that it can be used in an extended form or draped over a solid surface to contact a gaseous, liquid, or solid environment and can be manipulated for placement in a container where the absorbed analyte can be removed from the FPSE for instrumental analysis. The FPSE can have specific functionalities that bind to specific analytes or can provide a general sorbent medium for extraction of a wide range of analytes, such that the sampling device can be employed for sampling analytes with biological, environmental, food, pharmaceutical, bio-analytical, clinical, forensic, toxicological, national security, public health, and/or safety implications.
摘要:
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.

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

摘要:
An adsorbent of the present invention includes a support; and a protein having an adsorption site for adsorbing a target substance, in which the protein includes a reversible binding site and a covalent binding site, the support includes an orientation-controlling site forming a reversible bond with the reversible binding site, and an immobilization site forming a covalent bond with the covalent binding site, the covalent binding site includes a nucleophilic functional group, and the immobilization site includes a functional group capable of reacting with the nucleophilic functional group by a nucleophilic substitution or a nucleophilic addition. Thus, it is possible to provide an adsorbent in which the utilization efficiency of the adsorption site of the protein is improved. As a result, the protein amount can be reduced, and the step for storing a culture solution can be simplified due to the faster purification step.
