Abstract: The invention relates to a method for the sorption of at least one nucleic acid molecule from a liquid medium, comprising the following steps: (a) providing a liquid medium comprising at least one nucleic acid molecule; (b) providing a layer comprising at least one acid-activated phyllosilicate, where the layer is permeable by the liquid medium, and the layer thickness is at least 1 mm; (c) passing the liquid medium with the at least one nucleic acid molecule from step (a) through the layer from step (b) for sorption of the at least one nucleic acid molecule in the layer.

Abstract: A method for binding impurities in paper production, comprising the following steps: a) provision of a bentonite, the proportion of the monovalent cations, based on the cation exchange capacity (CEC) of the bentonite, being at least 0.7 and the CEC being more than 85 meq/100 g, preferably more than 90 meq/100 g, in particular more than 95 meq/100 g; b) addition of the bentonite according to a) to a paper pulp or fiber suspension; c) binding of the impurities to the bentonite in the pulp or fiber suspension is described.

Abstract: The invention relates to a process for producing granules and to a granule obtained by the process. In the process, a clay material is used which has a specific surface area of more than 150 m2/g, a pore volume of more than 0.45 ml/g and a cation exchange capacity of more than 15 meq/100 g.

Abstract: What is described is a slurry comprising (a) at least 10% by weight of at least one sheet silicate, based on the total weight of the slurry; (b) an aqueous suspension medium and (c) a dispersing aid selected from at least one polyethylene glycol having a mean molecular weight of less than 90 000 and/or at least one polyacrylic acid in free acid form. Also described is a process for producing the slurry and the preferred used thereof.

Abstract: The invention relates to a method for removing or recovering at least one nucleic acid molecule from an aqueous or alcoholic medium with the aid of a sorbent, where the sorbent includes at least one acid-activated sheet silicate, to a composition comprising the aforementioned sorbent, and to the preferred uses thereof.

Abstract: The invention relates to the use of a composition comprising stevensite or at least one stevensite-containing component for adsorption of mycotoxins. The invention further relates to an animal feed formulation and to a process for animal feed treatment, in which this composition is used.

Abstract: A description is given of an agent, in particular for adsorbing protein from protein-containing liquids in the food sector, comprising at least one smectitic layered silicate having a total cation exchange capacity of about 30 to 120 mVal/100 g, characterized in that the content of potassium ions is less than 50%, preferably less than 40%, but more than 8%, preferably more than 12%, of the total cation exchange capacity of the layered silicate. In addition, a description is given of a method for producing an adsorption agent, and also its preferred use.

Abstract: The invention relates to transparent organic/inorganic composites with low hydroxyl group content, based on silicic acid heteropolycondensates having extremely low water uptakes. These composites are obtained for example by nonhydrolytic condensation of chlorosilanes with polymerizable groups and optionally fluorinated groups, with the help of a condensation agent (e.g., t-butanol) capable of non-hydrolytic condensation of this chlorosilane, and thermal and/or photochemical polymerization of the obtained condensation product, preferably in the presence of preferably fluorinated organic monomers.
