Verfahren zur Herstellung von cellulosischen Formkörpern mit hohem Adsorptionsvermögen

摘要

The invention relates to a method for producing highly adsorbent cellulosic forms according to the dry-wet extrusion method by producing a solution of 5 to 20 mass % cellulose in a hydrous, tertiary amine oxide, extruding the solution, distorting the extrudate in a non-precipitating medium and precipitating the forms in an aqueous precipitation bath. The method is characterised in that a solution with 0.01 to 300 mass % in relation to the cellulose of at least one ion exchanger of particle size
