采用生物吸附法研究了真菌死亡生物量（Pleurotus mutilus）对稀水溶液中铀的去除和回收。对影响吸附铀（VI）的pH、温度、生物质粒径、搅拌速度等参数进行了研究和优化。采用伪一阶和伪二阶方程对实验数据进行了分析。Freundlich和Langmuir吸附模型被用于吸附平衡的数学描述。计算了铀的最大生物吸附量。得到的值（636.9 mg g−1）表明p。是一种很好的吸附剂。此外，还确定了铀链所涉及的化学带。将这种生物吸附法应用于实际的废铀渗滤液中，取得了满意的效果。
Removal and recovery of uranium from dilute aqueous solutions by dead fungal biomass (Pleurotus mutilus)have been studied by biosorption. The parameters that affect the uranium(VI) adsorption, such as: pH solution, temperature, biomass particle size and speed of stirring have been investigated and optimized. The experimental data were analyzed using pseudo-first-order and pseudo-second-order equations. The Freundlich and Langmuir adsorption models have been used for the mathematical description of the adsorption equilibrium. The maximum uranium biosorption capacity has been calculated. The value obtained (636.9 mg g−1) showed thatP. mutilusis a good adsorbent. Also, the chemical bands involved in uranium link have been identified. We have applied this biosorption to actual waste uranium leachate, the results are satisfactory and promising.
