  1. 240. Uranium extraction from seawater using radiation-grafted UHMWPE fiber: from laboratory to pilot scale
    Prof. Guozhong Wu (Shanghai Institute of Applied Physics, Chinese Academy of Sciences)

    Separation Methods, Speciation
    Invited
    Owing to the fast economic growing and the concern over greenhouse gases and air pollution, uranium extraction is one important option to meet the nuclear fuel consumption in the future. The uranium reserve is one thousand times that in land; however, the big challenge of feasibility is the extremely low uranium concentration in ocean (ca. 3.3-3.5 ppt). Polyethylene fiber modified by...

  2. 146. A Rapid Method for 236U Determination in Seawater
    Dr Jixin Qiao (Technical University of Denmark)

    Separation Methods, Speciation
    Verbal
    An automated analytical method implemented in a flow injection (FI) system was developed for rapid determination of 236U in 5-10 L seawater samples. After a quick iron hydroxide co-precipitation, extraction chromatography (UTEVA) was exploited to separate and purify target analytes, whereupon 238U was used as a chemical yield tracer. Accelerator mass spectrometry (AMS) was applied for...

  3. 121. Development of a Rapid Method to Determine Plutonium in Foodstuffs
    Dr Claudia Landstetter (Austrian Agency for Health and Food Safety)

    Separation Methods, Speciation
    Verbal
    After the Fukushima accident the development of rapid methods for foodstuff was getting more demanding in Austria. Therefore the Federal Ministry of Health financed a project for the development of a rapid method for the determination of plutonium in foodstuffs. Currently our lab determines plutonium just in environmental samples. This method takes about one week with ashing, dissolution,...

  4. 280. Sorption of Strontium Radionuclides from Seawater
    Dr Dmitry Marinin (Institute of Chemistry FEBRAS, Vladivostok, Russia)
    14/05/2014, 09:30
    Separation Methods, Speciation
    Verbal
    The development of nuclear power industry and nuclear technologies resulted in contamination of biosphere, including seawater areas and World Ocean at large, by various radionuclides. Radionuclide accumulation in seabed deposits and migration comprise a great danger for vital functions of different organisms. Strontium radionuclides belong to the group of toxic elements, which causes the...

  5. 50. Separation techniques for determination of actinides in various samples
    Dr LJUDMILA BENEDIK (Jožef Stefan Institute)
    14/05/2014, 09:45
    Separation Methods, Speciation
    Verbal
    Separation methods for determination of actinides applied at the Jožef Stefan Institute are described. Soil and sediment samples were decomposed by conventional wet dissolution with mixtures of HNO3, HClO4 and HF acids, microwave dissolution using HNO3 and HF, and alkaline fusion with Na2CO3 and Na2O2. while preconcentration of actinides from liquid samples was carried out by precipitation...
