摘要

本研究在台湾采集的地质材料上进行了铕(Eu(III))的吸附实验。对辉绿岩、玄武岩、花岗岩和生物岩进行的批量测试表明,辉绿岩和玄武岩对 Eu 具有强烈的吸附反应。X 射线衍射(XRD)分析也清楚地表明了吸附前后的差异。通过结合 X 射线吸收近边结构(XANES)、扩展 X 射线吸收精细结构(EXAFS)和小波变换(WT)分析,我们观察到在吸附 Eu 的过程中,Fe2O3 的含量会显著影响内球层中 Eu-Fe 的距离。针对二维信息的小波变换分析有助于区分难以分析的两种 Eu-O 距离,水合外球层 Eu-O 距离为 2.42 至 2.52 Å,内球层 Eu-O 距离为 2.27 至 2.32 Å。Fe2O3 依次与玄武岩、闪长岩和花岗岩形成内球表面络合,而 SiO2 则与玄武岩和闪长岩形成外球离子交换。小波变换分析也凸显了这些材料之间的差异。

Enhancing Europium Adsorption Effect of Fe on Several Geological Materials by Applying XANES, EXAFS, and Wavelet Transform Techniques.

This study conducted adsorption experiments using Europium (Eu(III)) on geological materials collected from Taiwan. Batch tests on argillite, basalt, granite, and biotite showed that argillite and basalt exhibited strong adsorption reactions with Eu. X-ray diffraction (XRD) analysis also clearly indicated differences before and after adsorption. By combining X-ray absorption near-edge structure (XANES), extended X-ray absorption fine structure (EXAFS), and wavelet transform (WT) analyses, we observed that the Fe2O3 content significantly affects the Eu-Fe distance in the inner-sphere layer during the Eu adsorption process. The wavelet transform analysis for two-dimensional information helps differentiate two distances of Eu-O, which are difficult to analyze, with hydrated outer-sphere Eu-O distances ranging from 2.42 to 2.52 Å and inner-sphere Eu-O distances from 2.27 to 2.32 Å. The EXAFS results for Fe2O3 and SiO2 in argillite and basalt reveal different adsorption mechanisms. Fe2O3 exhibits inner-sphere surface complexation in the order of basalt, argillite, and granite, while SiO2 forms outer-sphere ion exchange with basalt and argillite. Wavelet transform analysis also highlights the differences among these materials.

期刊介绍: The Journal accepts papers describing work that furthers our understanding of the exposure, effects, and risks of chemicals and materials in humans and the natural environment as well as approaches to assess and/or manage the toxicological and ecotoxicological risks of chemicals and materials. The journal covers a wide range of toxic substances, including metals, pesticides, pharmaceuticals, biocides, nanomaterials, and polymers such as micro- and mesoplastics. Toxics accepts papers covering: The occurrence, transport, and fate of chemicals and materials in different systems (e.g., food, air, water, soil); Exposure of humans and the environment to toxic chemicals and materials as well as modelling and experimental approaches for characterizing the exposure in, e.g., water, air, soil, food, and consumer products; Uptake, metabolism, and effects of chemicals and materials in a wide range of systems including in-vitro toxicological assays, aquatic and terrestrial organisms and ecosystems, model mammalian systems, and humans; Approaches to assess the risks of chemicals and materials to humans and the environment; Methodologies to eliminate or reduce the exposure of humans and the environment to toxic chemicals and materials.
