  A system for remediation of perfluoroalkyl substances (PFASs) has a multiplicity of β-cyclodextrins (β-CDs) and/or modified β-CDs combined with a vehicle additive, and a delivery device. Modified β-CDs can contain a single amine functionality at a single primary carbon or single secondary carbon of the β-CD. The vehicle additive can be powdered activated carbon (PAC). The delivery device is a column, a pouch, a packet, or a sheet that can permit the contacting of a fluid environment with the β-CDs and vehicle additive. The system of remediation can be used for a fluid environment or for biological organisms. CD-based fluorescent sensors can detect PFASs in the environment.

  一种用于修复全氟烷基物质（PFASs）的系统由多种 β-环糊精（β-CDs）和/或改性 β-CDs 与载体添加剂和输送装置组合而成。改性的 β-CD 可以在 β-CD 的单个伯碳或单个仲碳上含有单个胺官能团。载体添加剂可以是粉末活性炭（PAC）。输送装置可以是柱状、袋状、包状或片状，允许流体环境与 β-CD 和载体添加剂接触。修复系统可用于流体环境或生物有机体。基于 CD 的荧光传感器可以检测环境中的 PFAS。
