处理含低浓度但价值高昂的稀土元素（REEs）的废水是稀土分离和精炼行业的关键问题之一。在这项工作中，研究了自支撑花状纳米氢氧化镁（nano - Mg(OH)₂）与低浓度稀土废水之间的相互作用及相关机制。纳米氢氧化镁成功吸附了超过99%的稀土元素。进一步分析表明，稀土元素可以以金属氢氧化物纳米颗粒的形式聚集在氢氧化镁表面。
Treatment of wastewater containing low-concentration yet highly-expensive rare earth elements (REEs) is one of the vital issues in the REEs separation and refining industry. In this work, the interaction and related mechanism between self-supported flowerlike nano-Mg(OH)(2) and low-concentration REEs wastewater were investigated. More than 99% REEs were successfully taken up by nano-Mg(OH)(2). Further analysis revealed that the REEs could be collected on the surface of Mg(OH)(2) as metal hydroxide nanoparticles (
