Abstract

There is growing concern about the poisoning of groundwater with uranium (U) and other heavy metals. The efficacy of identifying a suitable adsorbent material for the elimination of heavy metals has been exemplified, including the utilization different plants as adsorbents. The experimental findings were examined by utilizing equilibrium isotherms, enabling the examination of the adsorption behavior of uranium on Rumex Acetosella. Based on the equilibrium data analysis such as the Langmuir, Freundlich and Sips, etc. isotherms demonstrate a strong correlation with the experimental data (R² > 0.90) which means high efficiency in isotherm behavior of the adsorbent.

芦笋对铀的吸附等温线及热力学模型研究

地下水被铀和其他重金属污染的问题日益引起人们的关注。举例说明了确定一种合适的吸附剂材料用于消除重金属的有效性，包括利用不同的植物作为吸附剂。利用平衡等温线对实验结果进行了检验，从而研究了铀在芦笋上的吸附行为。根据Langmuir、Freundlich和Sips等平衡数据分析，等温线与实验数据具有较强的相关性（R2 > 0.90），说明吸附剂的等温线行为效率高。图形抽象
