Summary

For the rapid removal of heavy metal impurities from large volumes of solutions, ion-exchange cellulose loose fibres have proved to be effective. Distilled water and absolute ethanol were purified by the column technique. For the checking of the effectiveness of the purification, analysis with carboxycellulose and neutron activation were used. The results were in good agreement. The purification is effective up to ppt concentrations.

Zusammenfassung

Zur Entfernung von Schwermetallverunreinigungen aus Flüssigkeiten großen Volumens entsprachen am besten die watte-förmigen Ionaustausch-Zellulosen. Wir haben destilliertes Wasser und absoluten Äthylalkohol von ihren Verunreinigungen in Kolonnen gereinigt. Zur Kontrolle der Wirksamkeit der Reinigung haben wir 1) die Carboxy-Zellulose-Analyse und 2) die Neutronen-Aktivierungsanalyse verwendet. Die Resultate der Methoden 1) und 2) stimmen gut überein. Die Reinigung ist bis zur ppt-Konzentration wirksam.
