Abstract
1. Process for preparing an anion exchanger, especially for the waste water treatment, comprising the treatment of cellulose derivatives with polyethylene imine in an aqueous reaction medium and recovery of the ion exchanger from the reaction mixture, characterized in that as cellulose derivative bark treated first with caustic alkali and subsequently with sulfuric acid is used and the treatment is carried out at a pH value of from 2 to 6.
