| titleOfInvention | Reagent and application thereof in hydrogen sulfide detection |
| abstract | The invention provides a reagent for detecting hydrogen sulfide (H2S), which is 5-azidofluorescein quinone. The reagent is prepared by reacting 5-aminofluorescein with sodium nitrate and sodium azide in acetic acid and water at room temperature for 2.5 hours. The method has the advantages of cheap raw materials and simple reaction conditions, and is easy for production. The invention provides a quantitative detection method of hydrogen sulfide, which can quantitatively detect the content of hydrogen sulfide in an acetonitrile/HEPES (4-(2-hydroxyethyl)-1-piperazineethanesulfonic acid) (pH 7.4) solution on the basis of 5-azidofluorescein quinone. The detection method has the advantages of high sensitivity and selectivity for hydrogen sulfides, simple, sensitive and quick detection process, and accurate detection result. |
