Infrared sensor for screening of emerging contaminants in water

项目摘要/摘要 该项目的目标是开发一种用于监测全氟烷基物质和多氟烷基物质(PFAS)的传感器 帮助普及和公平地为所有人提供安全和负担得起的饮用水。全氟辛烷磺酸 在过去的十年中，由于它们的持久性和生物累积性以及较高的 毒性。所提出的传感器是基于结合了先进纳米级技术的红外光谱技术 吸附材料用于污染物的预浓缩，实现高选择性和高灵敏度。这个 建议的技术可适用于便携式、自动化和成本效益高的野外水筛选 用于公共地表水或地下水处理厂的在线水质监测。这个

Project Summary/Abstract The goal of this project is to develop a sensor for monitoring of per- and polyfluoroalkyl substances (PFAS) in water to help achieve universal and equitable access to safe and affordable drinking water for all. PFAS have received particular attention in the past decade due to their persistent and bio-accumulative nature and high toxicity. The proposed sensor is based on infrared (IR) spectroscopy that incorporates advanced nano-scale adsorbent materials for pre-concentration of contaminants to achieve high selectivity and sensitivity. The proposed technology can be adapted for portable, automatable, and cost-effective screening of water in field conditions and for in-line water quality monitoring at public surface or ground water treatment plants.
