| titleOfInvention | A kind of method for detecting permanganate with coumarin-based probe |
| abstract | The invention provides a method for detecting permanganate with a coumarin-based probe. The coumarin-based probe described in the invention is a 2-oxo-2hydro-benzopyran-7-R base , which is obtained by condensation of 7-hydroxybenzopyran-2-ketone and acid chloride, and the response group of the probe to permanganate is a double bond. The single probe has no fluorescence in the mixed solution of organic solvent and water. When it is used for the detection of permanganate, it shows an obvious fluorescence light-on response, and the response time is less than 3 s, which can realize the real-time detection of permanganate; The detection sensitivity is high, and the detection limit is as low as 0.95 nmol/L; it has high selectivity for permanganate, and the standard curve can be used to accurately determine the permanganate content in water samples and non-standard explosive raw materials in the environment. It has excellent selectivity and sensitivity, can be used for rapid detection of permanganate on site, and has broad application prospects. |
