项目摘要

This award is funded under the American Recovery and Reinvestment Act of 2009 (Public Law 111-5).With this award from the Major Research and Instrumentation (MRI) program, Professor Diana Aga, Tracy Bank, Eliza S. Calder, Alan J. Rabideau and David F. Watson will acquire an Inductively Coupled Plasma Mass Spectrometer (ICP/MS) to be used for environmental science and engineering research. Projects that will be undertaken include: 1.) environmental impacts of engineered nanomaterials, 2.) biogeochemistry and remediation of heavy metal pollutants, 3.) geochemical analysis of volcanic rocks for petrological research, 4.) transport and modeling of strontium and phytoremediation of cadmium, and, 5.) characterization of semiconductor nanomaterials. Mass spectrometry (MS) is used to identify the chemical composition of a sample by measuring the mass of the molecular constituents in the sample after they are ionized and detected by the mass spectrometer. The ICP/MS will allow analysis of metal speciation at sub-parts per billion (ppb) levels, which is crucial in accurately assessing the effectiveness of bioremediation and the risks of metal contamination. It will not only be useful for environmental samples, but will also be a highly valuable characterization tool for nanomaterials research. The laser ablation system in front of the ICP/MS can be used for direct analysis of solid rocks and semiconductor materials. This will advance and transform the current research activities of students and in Geology and Chemistry.

该奖项由 2009 年《美国复苏和再投资法案》（公法 111-5）资助。获得该奖项的主要研究和仪器 (MRI) 项目包括戴安娜·阿加 (Diana Aga) 教授、特雷西·班克 (Tracy Bank)、伊丽莎·S·考尔德 (Eliza S. Calder)、艾伦·J·卡德 (Alan J. Rabideau 和 David F. Watson 将购买一台电感耦合等离子体质谱仪 (ICP/MS)，用于环境科学和工程研究。将开展的项目包括：1.) 工程纳米材料的环境影响，2.) 生物地球化学和重金属污染物的修复，3.) 用于岩石学研究的火山岩地球化学分析，4.) 锶的迁移和建模以及植物修复镉，以及，5.) 半导体纳米材料的表征。质谱（MS）用于通过测量样品中的分子成分被电离并被质谱仪检测后的质量来鉴定样品的化学成分。 ICP/MS 将能够以十亿分之几 (ppb) 的水平分析金属形态，这对于准确评估生物修复的有效性和金属污染的风险至关重要。它不仅对环境样品有用，而且也将成为纳米材料研究的非常有价值的表征工具。 ICP/MS 前面的激光烧蚀系统可用于直接分析固体岩石和半导体材料。这将推动和改变学生当前的地质学和化学研究活动。
