摘要：
The invention relate to a process for reducing the wash water required by weakly basic anion exchangers containing primary and/or secondary amino groups when fed with water containing carbon dioxide; in accordance with the process the exhausted, weakly basic anion exchangers are treated with dilute aqueous mineral acids before being regenerated.
