| titleOfInvention | A fluoride ion detection method based on chlorosilane derivatization |
| abstract | The invention discloses a fluoride ion detection method based on chlorosilane derivatization, comprising: adding inorganic acid to the sample for acidification, adding a silylating reagent with a boiling point range of 100-300°C, and reacting at 25-60°C for 5-60 minutes , the alkaline solution adjusts the pH value of the solution to be pH 7.0-10.0, and extracts with a water-insoluble organic solvent to obtain a silanization product solution; the obtained silanization product solution is subjected to gas chromatography or gas chromatography-mass spectrometry analysis and detection, and adopts Quantitative analysis of fluoride ion in aqueous solution by external standard method. The detection method adopts monochlorosilane with a higher boiling point, which increases the boiling point of the fluoride ion silanization product, improves the sensitivity, selectivity and accuracy of the detection method, and has relatively simple experimental operation and wide application. |
