Abstract

519,848. Purifying liquids. NORSK HYDROELEKTRISK KVAELSTOFAKTIESELSKAB. Oct. 3, 1938, No. 28713. Convention date, Aug. 23. 1938. [Class 46] [Also in Groups III and VIII] A base-exchange material is obtained by passing waste sulphite liquor through a hydrogencontaining base-exchange material, evaporating the effluent to dryness, exposing the dried residue to continued heating and finally washing it with boiling water.
