项目摘要

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.

项目概要/摘要该项目的目标是开发一种传感器，用于监测全氟烷基物质和多氟烷基物质（PFAS）水，以帮助所有人普遍和公平地获得安全和负担得起的饮用水。 PFAS 有由于其持久性和生物累积性以及高浓度，在过去十年中受到特别关注。毒性。所提出的传感器基于红外 (IR) 光谱，结合了先进的纳米级用于预浓缩污染物的吸附材料，以实现高选择性和灵敏度。这所提出的技术可适用于便携式、自动化且经济高效的现场水筛选条件以及公共地表水或地下水处理厂的在线水质监测。这
