The goal of the proposed work is a better understanding of crystal structures of Fe , Fe , Cu, and AI sulfates. These minerals commonly accompany environmental pollution generated by acidic waters, termed acid mine drainage (AMD). I propose to study a suite of selected Fe , Cu, and Al sulfates, Fe -Fe hydroxy-sulfates (so-called green rust), and AI polycationic salts (e.g., ¿-Keggin sulfate) by synchrotron X-ray and neutron diffraction. The results from diffraction studies will be complemented by 27Al nuclear magnetic resonance (on Al polycationic salts), 56Fe Mössbauer spectroscopy (green rust), and ab-initio density-functional theory calculations. Combination of these techniques will lead to exhaustive description of the crystal structures of the minerals associated with AMD. The results of this project will be applicable toward remediation efforts at sites polluted with AMD waters and acid rain.

建议的工作的目标是更好地了解铁，铁，铜和铝硫酸盐的晶体结构。这些矿物质通常伴随着由酸性沃茨产生的环境污染，称为酸性矿井排水（AMD）。我建议研究一套选定的铁，铜，铝硫酸盐，铁-铁 羟基硫酸盐（所谓的绿色锈），和Al聚阳离子盐（例如，Keggin硫酸盐）的同步加速器X射线和中子衍射。衍射研究的结果将由27铝核磁共振（铝聚阳离子盐），56铁穆斯堡尔光谱（绿色锈），从头算密度泛函理论计算。这些技术的组合将导致与AMD相关的矿物的晶体结构的详尽描述。该项目的结果将适用于AMD沃茨和酸雨污染场地的修复工作。
