The invention relates to a method of producing monodisperse amidomethylated vinylaromatic bead polymers, to ion exchangers prepared from these monodisperse amidomethylated vinylaromatic bead polymers by alkaline hydrolysis, to the method of using said monodisperse amidomethylated vinylaromatic bead polymers in the manufacture of ion exchangers and chelating resins, and also to the method of using these ion exchangers in the removal of heavy metals and noble metals from aqueous solutions or gases.

To provide a porous molding that can be used as a molding that has sufficient strength to be self-supportable even when the dimensions change due to absorbing water and that can be suitably used as a filter for removing impurities in a liquid or gas. A porous molding is achieved by sintering a mixed powder including a dried gel powder and a thermoplastic resin powder, wherein the ratio of average particle diameter d.sub.1 of the thermoplastic resin powder to the average particle diameter d.sub.2 of the dried gel powder d.sub.2/d.sub.1 is 1.3 or greater, and the difference ratio of average particle diameter d.sub.1 of the thermoplastic resin powder to the average particle diameter d.sub.2 of the dried gel powder and the average particle diameter d.sub.3 of the dried gel powder when absorbing water and swelling is (d.sub.3−d.sub.2)/d.sub.1 is 4.0 or less.

The invention encompasses resinate formulations comprising an agricultural active ingredient and an ion exchange resin, wherein the agricultural active ingredient is imbibed upon the ion exchange resin; and methods of treating an agricultural surface. The invention also encompasses methods of manufacturing an agricultural formulation comprising a resinate, comprising: providing an agricultural active ingredient and an ion exchange resin; and mixing the agricultural active ingredient and the ion exchange resin to imbibe the agricultural active ingredient upon the ion exchange resin, thereby forming the resinate.

Biologically activated ion-exchange polymer salts are made by exchanging biologically active ionic agents onto ion-exchange polymers. The activated polymers are uniquely surface active and stable to thermal degradation and chemical and other forms of decomposition. The activated ion-exchange polymer salts may be processed and combined with polymer precursors using novel methods and materials to produce stable, biologically activated polymer composites, including antimicrobial and antifouling polymer composites.

There is disclosed, a desalination apparatus making use of a particles including covalently bonded functionalized magnetic nanoparticles coupled to a complexing agent. For example, the complexing agent may include a crown ether. The particles are optionally used for removing salt from water, for example sea water. The apparatus optionally includes a magnet for magnetic filtering, concentrating and/or removing the particles and/or contaminant (e.g. salt). In some embodiments, the salt is then separated back from the particles using UV light. The remaining unclarified water may be washed out with the contaminant and/or used for salt production and/or disposed of (e.g. dumped back to the sea). Optionally, the particles are regenerated. For example, the regenerated particulars may be reused for further desalination steps (e.g. further salt removal from the clarified water) to clarify new input water.
