| titleOfInvention | Determination of nitrite content by MOF@PVP@PVDF composites |
| abstract | The invention belongs to the technical field of metal-organic framework materials, and in particular relates to a method for measuring nitrite content by using MOF@PVP@PVDF composite materials. The method includes the following steps: 1) preparing the MOF@PVP@PVDF composite material; 2) drawing a working curve; 3) detecting. Under the action of sulfuric acid, the amino group in MOF@PVP@PVDF reacted with NO 2 ‑ , resulting in a diazotization reaction, resulting in the fluorescence quenching of MOF, while PVP in the composite enhanced the stability of MOF in water, and PVDF enhanced the stability of MOF in water. The solubility of the material in water was determined by the change of its fluorescence spectrum. The method of the present invention has the characteristics of rapid response, high selectivity and high sensitivity for the determination of NO 2 - content. |
