VERFAHREN ZUR AUFARBEITUNG VON HYDROXYLAMIN ODER DESSEN SALZE ENTHALTENDEN ABWAESSERN

摘要

Wastewaters containing hydroxylamine or its salts are worked up by a process in which the said wastewaters are passed over a strongly acidic ion exchanger, after which a 5-15% strength by weight aqueous sulfuric acid is passed over the said ion exchanger and a solution of hydroxylammonium sulfate in aqueous sulfuric acid is obtained.
