DESCRIPTION (provided by applicant): Perchlorate, ClO4-, is a small highly water soluble anion created by both geogenic and anthropogenic sources. Anthropogenic sources include solid rocket fuel, matches, dyes, paints, airbag inflators, pyrotechnics, flares, and fertilizers. Human exposure to perchlorate is of concern because of the potential for impaired thyroid function, leading to a number of developmental delays and other medical problems. Most remediation projects rely on ion exchange resin bed reactors that operate in series as a fail-safe measure for when the first resin bed loses its ability to capture perchlorate, namely, its exhaustion-limit. Resin beds and resins are the largest cost item in the remediation process. If an online monitoring device could be developed that would warn operators of a bed reaching its exhaustion-limit, remediation efforts could operate more cost- effectively and with greater public safety. In our successful Phase I effort, Advanced MicroLab, LLC (AML) worked with the Prof. Henry Group at Colorado State University to transform a proof-of- principle laboratory experiment into a proof-of-concept commercial prototype for online analysis of perchlorate. Our prototype was field tested at a remediation pilot plant with our collaborators, Applied Research Associates (ARA). Testing post-remediated water, perchlorate was baseline resolved from interfering ions with < 1 5g/L limit-of-detection (LOD). Based on S/N, our device matched, if not out-performed, the gold standard, offline Ion Chromatography, in a side- by-side comparison. Additionally, we demonstrated resolution and reproducible detection of other ions in addition to perchlorate, such as, nitrate. In the proposed Phase II work, will transform a proof-of-concept prototype into a near- commercial demonstration unit meeting end-user specifications for online remediation processing. We will develop a companion field portable prototype for water source spot analysis in the field. We will also develop a companion analysis for nitrate and perchlorate from the same water sample. PUBLIC HEALTH RELEVANCE: The Department of Defense alone spends approximately $88 million annually on perchlorate-related research activities, including $60 million for perchlorate treatment technologies. In addition to remediation efforts, untold millions of dollars are spent to barricade contaminated sites and forcing to treat alternative non-contaminated water sources. The majority of the burden for the problem falls on the American citizen either through higher tax rates or municipal water rates. AML provides an innovative technology capable of significantly reducing these burdens through more cost-effective remediation efforts. Our market research conducted in collaboration with remediation technology experts concluded a typical remediation effort would save $0.65 - 1.73 million over a standard 20 year installation lifetime, which translates into a potential savings of $32.5 - 86.4M in California tax dollars alone. More importantly, remediation efforts would be safer, benefiting public health. Remediation facilities have been known to fail with resin release into the public water system. Embedding a monitor within the process can detect malfunctioning equipment or abrupt environmental changes and flag the problem at an early stage before other system components fail.

描述（由申请人提供）：高氯酸盐，ClO 4-，是一种小的高度水溶性阴离子，由地质和人为来源产生。人为来源包括固体火箭燃料、火柴、染料、油漆、气囊充气机、烟火、照明弹和化肥。人类接触高氯酸盐是令人担忧的，因为可能损害甲状腺功能，导致一些发育迟缓和其他医疗问题。大多数补救项目依赖于离子交换树脂床反应器，这些反应器串联运行，作为第一个树脂床失去捕获高氯酸盐能力时的故障安全措施，即其耗尽极限。树脂床和树脂是补救过程中最大的成本项目。如果能够开发出一种在线监测设备，在床达到耗尽极限时向运营商发出警告，那么补救工作就可以更具成本效益，并具有更大的公共安全性。 在我们成功的第一阶段工作中，Advanced MicroLab，LLC（AML）与科罗拉多州立大学的亨利教授小组合作，将原理验证实验室实验转化为概念验证商业原型，用于高氯酸盐的在线分析。我们的原型是现场测试的补救试点工厂与我们的合作者，应用研究协会（ARA）。测试后修复的水，高氯酸盐从干扰离子中基线分辨，检测限（LOD）<1.5g/L。基于S/N，在并行比较中，我们的设备与金标准离线离子色谱相匹配（如果性能不优于金标准离线离子色谱）。此外，我们证明了分辨率和重现性检测的其他离子，除了高氯酸盐，如硝酸盐。在拟议的第二阶段工作中，将把一个概念验证原型转变为一个接近商业化的示范装置，满足在线补救处理的最终用户规格。我们将开发一个配套的现场便携式原型，用于现场水源现场分析。我们还将开发一种对同一水样中硝酸盐和高氯酸盐的伴随分析。 公共卫生相关性：仅国防部每年就花费约8 800万美元用于与高氯酸盐有关的研究活动，其中6 000万美元用于高氯酸盐处理技术。除了修复工作外，还花费了数百万美元来封锁受污染的场地，并迫使处理替代的未受污染的水源。这个问题的大部分负担福尔斯都落在了美国公民身上，要么是通过提高税率，要么是通过提高市政水费。AML提供了一种创新技术，能够通过更具成本效益的补救措施来显著减轻这些负担。我们与修复技术专家合作进行的市场研究得出结论，在标准的20年安装寿命期内，典型的修复工作将节省65万至173万美元，仅在加州税收方面就可节省3250万至8640万美元。更重要的是，补救工作将更安全，有利于公众健康。已知补救设施因树脂释放到公共供水系统中而失效。在过程中嵌入监视器可以检测故障设备或突然的环境变化，并在其他系统组件故障之前的早期阶段标记问题。
