| titleOfInvention | Rare earth metal-organic framework fluorescent sensing material based on 2- (4-pyridyl) terephthalic acid, preparation method and application |
| abstract | The invention discloses a rare earth metal-organic framework fluorescent sensing material based on 2- (4-pyridyl) terephthalic acid, a preparation method and application, and belongs to the technical field of rare earth-organic framework material preparation, wherein the preparation method comprises the step of mixing 2- (4-pyridyl) terephthalic acid (H) 2 pta) is dissolved in distilled water, and rare earth nitrate Eu (NO) is added 3 ) 2 ·6H 2 O phase is filled into a polytetrafluoroethylene lining, then the polytetrafluoroethylene lining is placed into an oven, the temperature is kept constant at 150 ℃ and 170 ℃ for 24h, and then the temperature is reduced to room temperature at the speed of 2-4 ℃/h to obtain a target complex, and the complex can be used for detecting Fe 3+ The luminescence experiment shows that the quenching efficiency can reach more than 98 percent, and the quenching efficiency is higher than that of Fe 3+ The lowest detection line is 3.5 multiplied by 10 ‑5 mol/L, the invention can prepare products with higher purity and yield in a short time. |
