| Abstract: | The bio-adsorption of Uranium by yeast from alcohol solution and the effects of the experimental conditions are investigated.The experimental results show that the yeast is an efficient bio-adsorbent.The relationship between concentration of U in alcohol solution and adsorption capacity of U can be described by the Langmuir and Freundlich adsorption model.The uranium adsorbed by yeast can be desorbed 92.3% by 0.1N NaHCO 3. |
