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

0549220 wood本项目包括购买、安装和测试两套设备，用于分析爱达荷大学的天然水、岩石、土壤和实验室实验产品。这些仪器是：1)电感耦合等离子体原子发射光谱仪（ICP-AES），它可以测定地质样品中大多数低浓度的化学元素；离子色谱仪（IC），用于分析水中的阴离子，如氯化物和硫酸盐。这些仪器被爱达荷大学和附近的华盛顿州立大学的几组地球科学家使用，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、水文学家和土壤科学家。新的ICP-AES和IC支持地球科学的各种研究。这些研究包括，但不限于，有助于更好地理解：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体中的行为；3)地热系统中的断层水文；4)使用一组称为沸石的矿物来修复受放射性核素和重金属污染的水域；5)石棉在人体肺部的命运；6)极端环境下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)火山喷发样式；9)爱达荷州哈格曼化石床国家纪念碑的化石沉积环境。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，新仪器还以服务收费的方式提供给该地区的其他用户。重要的是，ICP-AES和IC用于培养分析地球化学的本科生和研究生。这些工具既用于正式的课程作业，也用于学生的研究项目。

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.
