| titleOfInvention | Method for rapidly detecting lead ions in sample liquid |
| abstract | The invention discloses a method for rapidly detecting lead ions in a sample liquid, which comprises the steps of carrying out sulfydryl modification treatment on the surface of a mesoporous alumina (AAO) membrane by using 3-mercaptopropyltriethoxysilane, enriching lead ions in a sample to be detected by using the modified mesoporous alumina (AAO) membrane, dropwise adding a methylamine bromide solution on the enriched mesoporous alumina (AAO) membrane to form methylamine lead bromoperovskite nanocrystals, detecting the fluorescence intensity of the generated methylamine lead bromoperovskite, and further detecting the content of the lead ions in the liquid to be detected. The method makes full use of the in-situ growth of MAPbBr 3 Perovskite has low fluorescence background, good specificity and high quantum yield, and mesoporous alumina (AAO) film is to MAPbBr 3 The perovskite has the characteristics of limited domain effect and the like, and the method is simple to operate, high in sensitivity, high in stability, good in selectivity, good in reproducibility and quick in lead ion analysis by combining the advantages of high sensitivity, convenient and quick detection process and the like of a fluorescence spectrum technology. |
