|Abstract:||After a radiological accident with dissemination of radioactivity, water is generally used to decontaminate urban areas. Around 100 litre water is used per square meter. The successful treatment of aqueous solutions containing small amounts of Cesium might allow for reuse of this water. Such a method needs to be robust, reliable and applicable with a minimum use of external energy. We applied a technique (i.e. ‘Ionfisher system’), which we discovered in 2006 for water treatment of water containing organic compounds, to capture small amounts (100ppm and 10ppm) of Cesium in water. For that we used combinations of both large molecules of water-soluble poly(alkylene oxide) with average molecular weights ranging from 9.0E+4 to 4.0E+6 and different types of clay.|
