| Popis: | Cupric ferrocyanide impregnated Bio-Rad AGMP-1 or Amberlite IRA-904 exhibited an excellent performance and could be repeatedly used for cesium sorption from 3M nitric acid in the presence of trace hydrazine and subsequent cesium desorption with 3–5M nitric acid containing a slight amount of nitrous acid when regeneration of the composite ion exchanger after the desorption was conducted with an acidic hydrazine solution containing cupric ion above 200–250 ppm. |
