Abstract: A process for removing Co2+, Pb2+, Cd2+ and Cr3+ toxins from bodily fluids is disclosed. The process involves contacting the bodily fluid with an ion exchange composition 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 exchange composition. The ion exchange compositions are represented by the following empirical formula: AmZraTibSncMdSixOy. A composition comprising the above ion exchange compositions in combination with bodily fluids or dialysis solution is also disclosed. The ion exchange compositions may be supported by porous networks of biocompatible polymers such as carbohydrates or proteins.

Abstract: A process for removing Hg2+ ions from a liquid stream is disclosed. The process involves contacting the liquid stream with specified UOP Zeolitic Materials. These molecular sieves are particularly effective in removing Hg2+ ions from aqueous streams even in the presence of Mg2+ and Ca2+ ions. The effective molecular sieves have an intermediate range of Si/Al ratios between about 2 and 20 and preferably between 3 and 10.

Abstract: A process for removing Hg2+ ions from a liquid stream is disclosed. The process involves contacting the liquid stream with specified ion-exchangers based on manganese oxides and metallomanganese oxides of the form An+wM3+xMn1-xO2 where A can be cations such as Na+ or Mg2+, M3+ can be metals such as Fe3+ or Co3+, and the TIC, the theoretical ion exchange capacity per framework metal atom, varies from 0.08 to 0.25. These ion-exchangers are particularly effective in removing Hg2+ ions from aqueous streams even in the presence of Mg2+ and Ca2+ ions.

Abstract: A method for preparing a family of zeolites, examples of which have been designated UZM-5, UZM-5P and UZM-6, and are represented by the empirical formula Mmn+Cgh+Rrp+Al(1-x)ExSiyOz The method includes forming a Charge Density Mismatch (CDM) reaction mixture comprising reactive sources of Al, Si, optionally a framework element, E, and at least one organic nitrogen containing cation template, C, in the hydroxide form. After the CDM mixture is mixed while aging, an organic cation crystallization template, R, and at least one alkali metal or alkaline earth metal, M, is added. The combined final reaction mixture is reacted with mixing to produce the zeolite, which may be used in various hydrocarbon conversion processes.
