【摘要】 初步探讨了啤酒酵母菌吸附铀的特性,考察了溶液pH值、铀的初始浓度等对吸附能力的影响,得出最佳pH值为6.0,结果表明:啤酒酵母菌对铀的吸附量大,由Langmuir吸附模型得出q_max=196.1mg/g,最后研究了铀的解吸,用Na₂CO₃或NaHCO₃解吸效果较好,解吸率分别为87.8％和87.2％。更多还原

【Abstract】 The biosorption of uranium from solution by saccharomyces ee.rrvisiae was studied. The effect of pH and the different initial concentration has been examined. The model of biosorption has been proved in agreement with Langmuir and Freundlich model by the connection of uranium equilibrium concentration and uptake. Results indicate that the maxium uptake can reach 196.1mg/g.更多还原
