Acquisition of an Inductively Coupled Plasma-atomic Emission Spectrometer and an Ion Chromatograph

这个项目涉及购买、安装和测试两台设备，用于分析爱达荷州大学的天然水、岩石、土壤和实验室实验产品。这些仪器包括：1)电感耦合等离子体原子发射光谱仪(ICP-AES)，用于在低浓度下测定地质样品中的大多数化学元素；以及2)离子色谱仪(IC)，用于分析水中的氯离子和硫酸盐等阴离子。爱达荷大学和附近华盛顿州立大学的几组地球科学家使用这些仪器，包括地球化学家、地球微生物学家、矿物学家、火成岩岩石学家、水文学家和土壤学家。新的电感耦合等离子体原子发射光谱和电感耦合等离子体发射光谱支持地球科学中的各种研究。这些研究包括但不限于有助于更好地理解以下问题的研究：1)铂族元素和钼的经济矿床是如何形成的；2)放射性核素在土壤和自然水中的行为；3)地热系统中的断层水文学；4)一组称为沸石的矿物在修复被放射性核素和重金属污染的水中的作用：5)石棉在人类肺中的去向；6)极端环境中生命的生物地球化学；7)微生物如何影响有毒金属硒和砷的地球化学；8)火山喷发的类型；9)爱达荷州哈格曼化石床国家纪念碑化石沉积的环境。所有这些项目都具有重要的社会经济应用。除了爱达荷大学和华盛顿州立大学的项目外，该地区的其他用户也可以按服务收费获得新仪器。重要的是，电感耦合等离子体原子发射光谱和离子交换技术被用于培养分析地球化学的本科生和研究生。这些仪器既用于正规课程作业，也用于学生研究项目。

0549220WoodThis project involves the acquisition, installation and testing of two pieces of equipment for the analysis of natural waters, rocks, soils, and products of laboratory experiments at the University of Idaho. The instruments are: 1) an inductively coupled plasma-atomic emission spectrometer (ICP-AES) which permits determination of most chemical elements at low concentrations in geological samples; and 2) an ion chromatograph (IC) which is used to analyze waters for anions like chloride and sulfate. These instruments are used by several groups of Earth Scientists at the University of Idaho and nearby Washington State University, including geochemists, geomicrobiologists, mineralogists, igneous petrologists, hydrologists and soil scientists. The new ICP-AES and IC support a variety of studies in the earth sciences. These include, but are not limited to, studies that contribute to a better understanding of: 1) how economic deposits of platinum-group elements and molybdenum are formed; 2) the behavior of radionuclides in soils and natural waters; 3) fault hydrology in geothermal systems; 4) the use of a group of minerals called zeolites in the remediation of waters contaminated with radionuclides and heavy metals: 5) the fate of asbestos in the human lung; 6) the biogeochemistry of life in extreme environments; 7) how microbes influence the geochemistry of the toxic metals selenium and arsenic; 8) the eruptive styles of volcanoes; 9) the environment of deposition of fossils at the Hagermann Fossil Beds National Monument in Idaho. All of these projects have significant socioeconomic applications. In addition to projects at the University of Idaho and Washington State University, the new instruments are available to other users in the region on a fee-for-service basis. Importantly, the ICP-AES and IC are used to train undergraduate and graduate students in analytical geochemistry. The instruments are employed both in formal course work and student research projects.
