| Popis: | Two chemical processes involving precipitation of cesium from waste solutions with iron(II)hexacyanocobaltate(III) and triphenylcyanoborate have been conducted. Various parameters have been investigated such as pH, molar ratio of Fe2+/Co(CN) 6 3− , molar ratio of triphenylcyanoborate to cesium and the nature of the simulated wastes. High percentage of cesium removal from different waste solutions has been achieved by using iron(II)hexacyanocobaltate(III). Precipitation of cesium with triphenylcyanoborate depends mainly on the concentration of triphenylcyanoborate and cesium as well as the molar ratio in solution. Triphenylcyanoborate can be used as a selective precipitant for cesium in both acidic and alkaline solution of pH not more than 10. |
