| Popis: | A number of impregnated sorbents based on di-(tert-butyldibenzo)-18-crown-6 (DTBDB18C6) and di-(tert-butylcyclohexano)-18-crown-6 (DTBDCH18C6) was obtained using different diluents for the crown ether and the styrene–divinylbenzene support. Sorption characteristics of the sorbents in relation to cobalt ions and 60Co radionuclide in thiocyanate solutions were determined within the range of pH of 1–7. It was found the DTBDB18C6-based sorbents were the most efficient for the sorption of cobalt macro quantities whereas the DTBDCH18C6-based ones for the sorption of 60Co radionuclide, using nitrobenzene as a diluent. A possibility was shown of the complete cobalt desorption by hydrochloric and nitric acid solutions with the concentration of 0.1–1.0 mol L–1. |
