| titleOfInvention | Covalent organic framework fluorescent test paper for detecting palladium ions in water and preparation method thereof |
| abstract | The invention provides a covalent organic framework fluorescent test paper for detecting palladium ions in water and a preparation method thereof, and belongs to the field of environmental detection. The XB-COF of the present invention is obtained from the monomer mes-trityl aldehyde and 2,5-bis(allyloxy) terephthalic hydrazide through a Schiff base reaction, using a solvothermal method; the XB-COF of the present invention is obtained by The acylhydrazone linkage improves the crystallinity, porosity and chemical stability of the material. XB-COF exhibited strong fluorescence when dispersed in water, and the strong fluorescence of XB-COF was quenched after the allyl group in XB-COF could interact with Pd 2+ to form COF-Pd ligands. The sensitive fluorescence changes and regular allyl active sites enable XB-COF to be used to construct high-performance fluorescent sensors for the detection of Pd 2+ with high sensitivity, high selectivity, and high stability. The fluorescent test paper of the present invention is based on a material grown on the filter paper in situ by XB-COF. The fluorescent test paper of the present invention can detect trace amounts of Pd 2+ in water, and can quickly detect industrial wastewater, organic synthesis reactions, pharmaceutical industry, etc. Presence of Pd 2+ in wastewater. |
