Abstract
Przedmiotem wynalazku jest sposób selektywnego wydzielania metoda chromatograficzna uranu z napromienionego w reaktorze jadrowym materialu zawierajacego tor (Th). Sposób oddzielenia mikroilosci uranu (U) i protaktynu(Pa) od makroilosci innych skladników (zwlaszcza Th) polega na tym, ze próbke zawierajaca U, Th i Pa rozpuszcza sie przy uzyciu roztworu HNO3 + HF + Al(NO3)3 w szczelnie zamykanym naczyniu wykonanym z politetrafluoroetylenu lub pochodnych teflonu (PTFE, PFA), naczynko szczelnie zamyka i ogrzewa w temperaturze 40-120°C, przez 1-24h. Po tym czasie uzyskuje sie klarowny roztwór. Nastepnie otrzymany roztwór wprowadza sie na kolumne chromatograficzna wypelniona tlenkiem trójoktylofosfiny (TOPO) naniesionym na nosnik hydrofobowy i prowadzi elucje. Na kolumnie pozostaje zatrzymany ilosciowo 233Pa. Wyciek z kolumny zawierajacy Th i U przenosi sie ilosciowo do naczynia z politetrafluoroetylenu (PTFE lub PFA) i odparowuje na plytce grzejnej pod wyciagiem, dodaje H2O, a nastepnie otrzymany roztwór nanosi sie na kolumne wypelniona amina alifatyczna czwartorzedowa, prowadzi elucje zbierajac frakcje uranu wymywanego ilosciowo w pierwszych pieciu frakcjach, korzystnie czterech frakcjach, a nastepnie Th we frakcjach 7-25.
