Rare earth elements (REEs) are utilized in numerous disciplines, including chemical engineering, the nuclear industry, metallurgy, medicine, electronics, and computer technology. Recycling products containing and extracting them from effluent is necessary to satisfy the rising demand for these elements. Some studies investigate the adsorption of rare earth elements from dilute aqueous solutions to remove them from effluent. Based on the results of this study, it can be concluded that lab tests demonstrate high adsorption capacities, which vary widely depending on the adsorption type and conditions. The Langmuir, Freundlich, and Temkin isotherms usually describe adsorption isotherms. In addition, the finest models for describing adsorption kinetics are pseudo-second-order and pseudo-first-order models. The thermodynamic parameters, such as the changes in free energy, enthalpy, and entropy, provide additional information regarding the energy changes. Additional research is required to develop environmentally friendly adsorbents that can be used to remove REEs from actual mine wastewater.

稀土元素 (REE) 用于许多学科，包括化学工程、核工业、冶金、医学、电子和计算机技术。为了满足对这些元素不断增长的需求，有必要回收含有它们的产品并从废水中提取它们。一些研究研究了从稀水溶液中吸附稀土元素以将其从废水中去除的方法。根据本研究的结果，可以得出结论，实验室测试表现出较高的吸附能力，但吸附能力因吸附类型和条件而异。 Langmuir、Freundlich 和 Temkin 等温线通常描述吸附等温线。此外，描述吸附动力学的最佳模型是伪二阶和伪一级模型。热力学参数，例如自由能、焓和熵的变化，提供了有关能量变化的附加信息。需要进行更多研究来开发可用于从实际矿山废水中去除稀土元素的环保吸附剂。
