PFI:AIR - TT: A FIELDABLE SPECIATION-CAPABLE GREEN ANALYZER FOR ARSENIC

这个PFI：空气技术翻译项目专注于翻译NSF赞助的砷测定及其化学形态的基础研究，以满足现场实时测定地下水砷的需求，以确定地下水是否受到砷的有毒水平的污染并确定其类型。该项目将产生一种便携式、手持式、“绿色”的现场可用砷分析仪原型。该仪器具有以下独特功能：(A)它可以区分毒性较高的亚砷酸盐和毒性较低且更容易去除的亚砷酸盐；(B)它可以测量这两种物质，精度可达百万分之几以下；(C)它是一种真正的绿色分析仪，使用空气、水和电力，含有少量可以回收利用的硫酸；以及(D)它在非常低的外形尺寸下提供强大的性能。这些特点提供了低成本和便携性、高灵敏度、低功耗和非常低的消耗品成本的优势，与这一市场领域目前可用的砷电化学仪器相比。该项目解决了在从研究发现到商业应用的过程中，将最初的台式概念验证转换为具有小而有吸引力的外形系数的仪器的技术差距。该项目与Chipotle Business Group Inc.合作，以增强他们的水分析能力，在开发期间为设备提供现场测试环境，进行市场研究，以确定客户群，并在这项技术转换工作中为仪器开发商业化途径。这种绿色的砷分析仪非常重要，因为它架起了学术分析仪器和低成本商业设备之间的桥梁，将有助于人类。这项技术将帮助数百万人，特别是来自世界各地发展中国家的人，他们面临着受到砷中毒影响的风险，砷中毒是通过饮用水长期接触砷造成的。砷是地球上第20大最丰富的元素？S地壳。即使在发达国家，也有许多地下水砷浓度较高的地区；这项技术将有助于执行水质控制条例和监测除砷工作的效果。

This PFI: AIR Technology Translation project focuses on translating NSF sponsored fundamental research in arsenic determination and its chemical speciation to fill the need for on-site real-time arsenic determination of ground water to determine whether or not it is contaminated with toxic levels of arsenic and to determine the type. The project will result in a portable, hand-held, "green" field-ready arsenic analyzer prototype. This instrument has the following unique features: (a) it can differentiate between the more toxic arsenite from the less toxic and more easily removable arsenate (b) it can measure both down to sub parts per billion levels, (c) it is a true green analyzer that uses air, water and electricity, with a small amount of sulfuric acid that can be recycled, and (d) it offers robust performance within a very low form factor. These features provide the advantages of low cost and portability, high sensitivity, low power consumption and very low cost of consumables when compared to the electrochemical instruments for arsenic currently available in this market space. This project addresses the technology gap of converting the original bench-top proof-of-concept to an instrument with a small, attractive form factor in a user-friendly form as it translates from research discovery toward commercial application.The project engages Chipotle Business Group Inc. to augment their water analysis capabilities, provide field testing environment for the device during development, conduct a market study to identify customer segments, and develop pathways to commercialization for the instrument in this technology translation effort.This green analyzer for arsenic is important because it bridges the gap between an academic analytical instrument and a low-cost commercial device that will help humanity. This technology will help the millions of people, especially from the developing countries across the world, who are at the risk of being affected by arsenicosis, which is caused by chronic arsenic exposure through drinking water. Arsenic is the 20th most abundant element in the earth?s crust. Even in developed countries there are many areas where groundwater arsenic concentration is high; this technology will be helpful in implementing water quality control regulations and monitoring the efficacy of arsenic removal efforts.
