| titleOfInvention | Electrochemical detection method for content of fluorine ions in tap water |
| abstract | The invention belongs to the field of electrochemical sensing, and particularly discloses an electrochemical detection method for the content of fluoride ions in tap water, which comprises the following steps: diluting tap water with an electrolyte solution containing charged probe molecules to serve as a detection solution, then taking an electrode modified by a phenylboronic acid functionalized silicon dioxide nano-mesoporous film as a working electrode, and detecting fluorine ions in the tap water solution by adopting an electrochemical voltammetry. According to the method, phenylboronic acid molecules and fluorine ions are combined to form tetrahedral borate anions, so that negative charges inside the pore canal are enhanced, probe molecules with negative charges are prevented from entering the pore canal or molecules with enhanced positive charges enter the pore canal, and quantitative detection of the fluorine ions in tap water is realized by recording changes of external probe molecule signals. The sensor constructed by the invention has high sensitivity, wide detection linear range and low detection limit, does not need to carry out complex pretreatment on a sample, and has great application potential in the field of drinking water safety monitoring. |
