摘要： 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.

摘要： A process for removing Hg2+ toxins from bodily fluids is disclosed. The process involves contacting the bodily fluid with a titanium metallate ion exchanger to remove the metal toxins in the bodily fluid, including blood and gastrointestinal fluid. Alternatively, blood can be contacted with a dialysis solution which is then contacted with the ion exchanger. The titanium metallate ion exchangers are represented by the following empirical formula: AmTiNbaSixOy. A composition is provided with the combination of the titanium metallate ion exchanger and bodily fluids or dialysis solutions. Also, provided is an apparatus comprising a matrix and the titanium metallate ion exchanger.

摘要： A water absorption treatment material includes a core portion and a coating portion. The core portion is approximately circular column-shaped and has a side surface, a first bottom surface, and a second bottom surface. The coating portion is provided so as to cover the core portion. A region of 80% or more of the side surface of the core portion is covered by the coating portion. A region of 80% or more of the first bottom surface of the core portion is exposed without being covered by the coating portion.
