An ammonia adsorption product is described which may be used for fresh caught fish and bait. The product may comprise functionalized tectosilicate compound and a buffer. High concentrations of ammonia produced by fish waste can be lethal, even though oxygen availability is rich enough to keep fish breathing. The product is a user-friendly, sustainable, affordable product which is able to extend the life of the fish by safely removing ammonia by an ion-exchange mechanism. This product can convert toxic ammonia into ammonium and uptake ammonium by releasing sodium ions in the water.

A composition for making composite adsorbents from a mixture of geopolymer, zeolite and activated carbon wherein a geopolymer material, a carbonaceous material, and an alkali activating agent are the components of the mixture. The alkali activating agent to carbonaceous material solid mass ratio is at least 0.25:1, respectively. A process for producing shaped composite adsorbents from the composition is done using conventional means such as mixing, shaping, extrusion and other methods. Alkali activation is used to convert the carbonaceous material to activated carbon, followed by hydrothermal treatment to convert the geopolymer material to zeolites. Shaped composite adsorbents fabricated from the composition of the instant invention are used for adsorption, purification, or other separation applications of liquids and gases.

A medical macromolecular microsphere adsorbent for a blood perfusion apparatus and a preparation method thereof are provided. The polystyrene-divinylbenzene microspheres are graded by different pore sizes and specific surface areas, medically purified, and grafted by a bioactivity-controlled grafting technology. In the microsphere adsorbent, the volume ratio of microspheres with pore sizes of 1-10 m, 10-100 m and 100 m is 1:(1-10):(1-20), the content of residual monomers in the microsphere has O.D.sub.190-400 nm0.03. The microsphere adsorbent not only can adsorb harmful micromolecules in blood but also can effectively adsorb harmful medium-molecules and macromolecules in blood, thereby meeting clinical application demands.

The present invention relates to a molecularly imprinted polymer for binding glycans, wherein the molecularly imprinted polymer is obtainable by providing a saccharide template such as a glycan; providing at least two functional monomers capable of cooperatively; interacting with the template; providing a crosslinking monomer; polymerizing the monomers optionally dissolved in a solvent, in presence of the saccharide template; and removing the template from the formed polymer. The invention is also related to a method for their production and use of the molecularly imprinted polymer.

A powdered Iron-Selenide-Oxide sorbent composition, a method of using the sorbent, and a method for producing the sorbent is disclosed for removing mercury vapor from a gaseous stream. The exact ratios of Fe to Se are varied. The method for producing the sorbent comprises the steps of: preparing a base ferrous or ferric oxide (FeO.sub.x) media, conditioning the FeO.sub.x media with a slurry of ferrous selenite (FeSeO.sub.3)/ferrous selenate (FeSeO.sub.4), reducing the FeSeO.sub.3/FeSeO.sub.4 mixture by an elemental iron (Fe.sup.0) powder to incorporate selenide into the slurry, and dewatering and oxidizing the slurry. The sorbent can be used alone (or in combination with a powdered activated carbon material or an inert powdered material) by direct injection into the Hg-containing gas stream, by coating of a filter fabric used in bag house with the sorbent, or by using the sorbent in a packed bed gas stream filtration system.

This invention introduces a method of preparing a carbon-based sulfur-loading iron-containing adsorbent for mercury removal, which can solve the problems in the prior art that sulfur-rich heavy organic materials have low-value utilization and the elemental mercury in atmosphere is hard to be efficiently and economically removed by the existing mercury removal agents. A carbon-based sulfur-loading iron-containing adsorbent for mercury removal is prepared in this invention. The adsorbent with a porous structure is prepared in situ by performing steps such as chemical activation of sulfur-rich heavy organic materials that are rich in iron. The adsorbent prepared herein has good mercury removal performance in simulated coal-fired flue gas. This invention not only improves the utilization value of sulfur-rich heavy organic materials, but also prevents SO.sub.X pollution caused by the combustion of sulfur-rich heavy organic materials and controls mercury pollution in the coal-fired flue gas.

The present invention relates to zeolitic adsorbents based on small agglomerated crystals of zeolite X comprising barium, combining optimum properties in terms of selectivity and of mechanical strength. These adsorbents have applications in the separation of fractions of aromatic C.sub.8 isomers and in particular xylenes, in the separation of substituted toluene isomers, such as nitrotoluene, diethyltoluene or toluenediamine, in the separation of cresols and in the separation of polyhydric alcohols, such as sugars.

The present invention relates to a process for taking up one or more nitrogen oxide(s) from a gaseous and/or aerosol or liquid medium using at least one particulate earth alkali carbonate-comprising material and/or at least one particulate earth alkali phosphate-comprising material as well as an adsorbing material comprising said at least one particulate earth alkali carbonate-comprising material and/or at least one particulate earth alkali phosphate-comprising material.
