Preparation and Properties of Rhodamine 6G/Polyethyleneimine Modified Cellulose Nanocrystals
摘要
Abstract
The sensor CNC-PEI-R6G was prepared by chemically modifying cellulose nanocrystals(CNC)with rhodamine 6G-polyethyleneimine(R6G-PEI).The compositional structure and detection performances of CNC-PEI-R6G were characterized by analysis methods of FT-IR,XRD,XPS,UV-vis,and PL.It was found that oxidation time had a significant influence on the content of aldehyde groups in D-CNC.With the addition of Fe3+,CNC-PEI-R6G solutions turned pink,and the fluorescence intensity at 566 nm was significantly enhanced,realizing naked-eye detection and fluorescence selective recognition of Fe3+in aqueous media,and the detection limit was 0.03 mg/kg.In addition,CNC-PEI-R6G can also be used to accurately identify Fe3+in actual water samples such as tap water and swimming pool water.关键词
