Abstract

Nanoplastics(NPs)in aqueous environment have become a category of emerging pollutants on account of their potential risks to both human health and environment.The detection of NPs is a great challenge due to the lack of sensitive and selective sensing materials with fast response time and wide sensing range of particle sizes.Herein,a Tb-based coordination polymer has been synthesized for luminescent detection of nanopolystyrene with different particle sizes in aqueous solutions,showing a low limit of detection,fast response time within 10 s and high selectivity in the presence of other plastics.The"turn-on"sensing mechanism is studied in detail.This work provides a facile method for the fast detection of NPs.
