| titleOfInvention | Fluorescent probe for identifying mercury ions and preparation and identification methods thereof |
| abstract | The invention discloses a fluorescent probe for identifying mercury ionsThe preparation method comprises dissolving 4-bromobenzaldehyde in ethanol to obtain A; dissolving 2-acetylpyridine, potassium hydroxide and ammonia water in ethanol to obtain B; mixing the A substance and the B substance, precipitating and filtering after reaction, and recrystallizing in acetic acid to obtain C; adding the C substance, 4-pyridine ethylene, palladium acetate and triphenylphosphine into triethylamine for mixing, and sealing the mixture in N 2 Reacting in a high-pressure reaction bottle in the atmosphere, dissolving the product in chloroform, then spin-drying, and recrystallizing with ethanol to obtain D; and adding the D substance into N, N-dimethylformamide for dissolving, then adding 6-bromohexanoic acid for reaction, adding diethyl ether into the reaction solution until the reaction solution is completely precipitated, performing suction filtration, washing twice with diethyl ether, and drying to obtain the fluorescent probe for identifying mercury ions. The method can realize qualitative and quantitative analysis of mercury ions, and has the characteristics of low identification cost, simplicity in operation, visual result, high sensitivity, good selectivity and the like. |
