摘要/Abstract

摘要： 稀土元素在铝(氢)氧化物矿物表面的吸附过程对铝土矿中稀土元素的富集和以吸附态存在的稀土元素的提取回收均具有重要影响。本文选择勃姆石作为研究对象,La和Y分别作为轻稀土和重稀土元素的代表,以批实验的方法,探究吸附时间、溶液pH值和背景电解质对勃姆石吸附稀土离子的影响。研究发现:勃姆石吸附稀土离子在72 h内能够接近平衡,对La³⁺和Y³⁺的吸附率分别约为45%和35%;在所选pH值范围内吸附率随pH值增加而升高;同时,吸附率随背景电解质浓度增加而升高。由于质子化效应,在弱酸性条件下,勃姆石表面携带正电荷,与稀土离子之间存在静电斥力,稀土离子与勃姆石之间可能形成内圈络合物。通过对比轻稀土和重稀土的吸附行为发现,勃姆石对轻稀土有更强的吸附能力。此外,通过热力学和动力学模型拟合分析发现,勃姆石对稀土离子的吸附更符合Langmuir单层吸附模型和准二级动力学模型。

Abstract: The adsorption process of rare earth elements on the surface of aluminum (hydrogen) oxide minerals has an important impact on the enrichment of rare earth elements in bauxite and the extraction recovery of rare earth elements in the adsorbed state. In this research, boehmite was selected as the model mineral, and La and Y were chosen as the representatives of light and heavy rare earth elements, respectively. The effects of adsorption time, solution pH value and background electrolyte concentration on the adsorption of rare earth ions on boehmite were investigated by batch experiments. The results show that the adsorption of rare earth cations by boehmite approaches equilibrium within 72 h, and the adsorption rates of La³⁺and Y³⁺ are about 45% and 35%, respectively. In the selected pH value range, the adsorption rate and the background electrolyte concentration rise with the increase of pH value. Due to the protonation effect, the surface of boehmite possesses positive charges under weakly acidic conditions, and electrostatic repulsion occurs between rare earth cations and the surface. So it can be speculated that inner-sphere complexes may be formed between rare earth elements and the surface of boehmite. Compared with heavy rare earth cations, boehmite is more likely to uptake light rare earth cations. The adsorption behavior of rare earth elements by boehmite is fitted better by Langmuir monolayer adsorption model and the pseudo-second-order kinetic model.

Key words: boehmite, rare earth element, adsorption, potentiometric titration, aluminum (hydrogen) oxide material, batch experiment
