Summary

The effect of pH on the sorption of ruthenium-97 on Fe2O3, Fe(OH)3 and Fe(OH)2 precipitates was studied by radiotracer technique. The sorption characteristics of Fe2O3, Fe(OH)3 and Fe(OH)2 sorbents have been established. Iron(II) hydroxide can be used for the preconcentration of ruthenium-97 or generally of trace amounts of ruthenium, without regard to the oxidation state of ruthenium. The effect of duration of the contact between the hydroxide sorbent and ruthenium-97 in solution was also studied.

Zusammenfassung

Der Einfluß des pH auf die Adsorption von97Ru an Fe2O3,- Fe(OH)3-und Fe(OH)2-Niederschlägen wurde radiochemisch untersucht. Die Sorptionsmerkmale der erwähnten Adsorptionsmittel wurden festgestellt. Eisen-(II)hydroxid kann für die Anreicherung von97Ru oder allgemein von Rutheniumspuren ohne Rücksicht auf deren Oxydationsstufe verwendet werden. Der Einfluß der Berührungsdauer zwischen adsorbierendem Hydroxid und97Ru in der Lösung wurde gleichfalls untersucht.
