摘要： Composite reactive articles are useful for quantifying cyanide ions in solution. The composite reactive articles can be porous reactive supports comprising an inert substrate having immobilized thereon finely divided gold. The porous reactive supports can be particulate, porous fibrous membranes, or solution-cast membranes. Alternatively, the composite reactive articles can comprise porous fibrous membranes having enmeshed therein the aforementioned porous supports which can be in particulate or fibrous forms. The method for quantifying cyanide ions in solution comprising the steps of contacting and passing a solution containing cyanide ions through a reactive support comprising a porous, high surface area, inert substrate on which is immobilized finely divided elemental gold at a controlled rate to provide for a time to provide sufficient contact time for the gold and cyanide ions to react and provide a soluble gold cyanide complex, recovering the effluent comprising said gold cyanide complex, and determining the quantity of cyanide present in the gold cyanide complex.

摘要： Composite articles are useful for separating mercury from fluids. The composite articles can be porous supports comprising an inert substrate having immobilized thereon finely divided gold optionally in combination with a tin salt coating. The porous support can be a particulate or porous fibrous webs. Alternatively, the composite articles can comprise a porous fibrous membrane having enmeshed therein the aforementioned porous supports which can be in particulate or fibrous forms. The method for separating elemental, ionic, or organic mercury in fluids comprises the step of contacting and passing a fluid containing mercury through a support comprising a porous, high surface area, inert substrate on which is immobilized finely divided elemental gold at a controlled rate for a time sufficient for the mercury to sorb to the elemental gold and to provide an immobilized gold-mercury amalgam on the support. If a tin salt also is immobilized on the inert substrate, mercury-tin salt can also be formed. In a further, and optional, step, elemental mercury can be removed from the support and optionally can be quantified.

摘要： Polymeric beads and methods of making the polymeric beads are described. The polymeric beads are crosslinked hydrogels or dried hydrogels. The polymeric beads are formed from droplets of a precursor composition that are exposed to radiation. The droplets are totally surrounded by a gas phase. The precursor composition contains a polar solvent and a polymerizable material miscible in the polar solvent. The polymerizable material has an average number of ethylenically unsaturated groups per monomer molecule equal to at least 1.2.

摘要： Insolubilized enzyme particulates are located on the upstream surface of a filtration layer of a filtering element which can be used in a cartridge filter. Employed in a recycling flow reaction system at relatively high flux rates, the cartridges are useful for conducting catalyzed chemical reactions of dissolved solutes, for example, esterifications, isomerizations, oxidations, reductions, and cyclizations.
