摘要:
A sorbent for sorbing radioactive ions is described. The sorbent comprises a porous crystalline powder of a metal oxide or mixed metal oxide. A process for making the sorbent comprises the steps of reacting a metal halide or a mixture of metal halides and an alcohol to form a gel; heating the gel to form a particulate material; exposing the particulate material to an oxidant to form a powder; and heating the powder to a temperature sufficient to at least partially melt or sinter particles of the powder so as to form the sorbent.

Um ein wirtschaftliches Verfahren zur Aufreinigung oder Extraktion von Analyten, die in komplexen, insbesondere unpolaren Stoffgemischen vorliegen, zu schaffen, wird vorgeschlagen dass das Stoffgemisch in einem wasserfreien Medium auf eine mit Hydrazingruppen funktionalisierte Festphase aufgebracht, das Medium wieder abgetrennt sowie anschließend die Festphase mit organischem Lösungsmittel gewaschen wird und dass nach dem Waschen die Festphase mit einer Mischung aus organischen Lösungsmittel und wässriger Säure zur Freisetzung der Carbonylverbindung eluiert wird, wobei die Carbonyl- Verbindung gelöst in dem organischen Lösungsmittel und der wässrigen Säure erhalten wird.

摘要:
Adsorbents for removing chlorides, bromides and iodides from water, which are based on silver-cation-doped aerogels. The proposed system is geared principally to the removal of bromide and iodide anions from drinking water and also to obtaining water of high purity.
摘要:
The invention relates to a method for treating the risk of accumulating C-reactive protein (CRP) by performing an extracorporeal perfusion of blood plasma of patients presenting a risk of cardiovascular diseases or immune dysfunctions such as autoimmune diseases by means of an apparatus, e.g. a column, which contains absorbent matrix material including lipids, peptides, polypeptides, phosphocholine (PC), or PC derivatives, in order to eliminate C-reactive protein. The invention further relates to the use of compounds which have the property of at least temporarily binding CRP in order to eliminate CRP from a patient's biological liquids so as to prevent and/or treat autoimmune diseases, cardiovascular diseases such as myocardial infarction, stroke, diabetes, rheumatism, and renal insufficiency.
摘要:
Disclosed is a method for activating a solid support material with epoxy groups and for immobilising ligands thereon, utilising phase transfer catalytic conditions. The method permits the introduction of epoxy groups and specific nucleophilic ligands on the support material with a high level of substitution. Furthermore, the invention provides a general method for immobilising a ligand for use in a wide variety of chromatographic separation procedures such as ion exchange chromatography, hydrophobic interaction chromatography (HIC), reverse phase chromatography (RPC), or affinity chromatography.
