Abstract
Методът включва отделяне на аминооксиди, по-специално на n-метилморфолин от воден разтвор, по-специално от отпадъчни води, които се получават при преработката на целулоза, като разтворите влизат в контакт с катионобменна смола, чиито свързващи груписе състоят от карбоксилни групи. След това заредената катионобменна смола се промива и аминооксидите се обработват с воден разтвор на слаба киселина с рка стойност, по-голяма от 3,0, като елуент.The method involves the removal of amine oxides, in particular of n-methylmorpholine from an aqueous solution, in particular from waste water which is produced by the pulping of the pulp, and the solutions come into contact with a cation exchange resin, the binding groups of which consist of carboxyl groups. The charged cation exchange resin is then washed and the amine oxides treated with an aqueous solution of weak acid with a pH of greater than 3.0 as eluent.
