Coumarin functionalized graphene oxide reversible fluorescent probe and preparation method and application thereof |
| abstract |
A coumarin functionalized graphene oxide reversible fluorescent probe and a preparation method and application thereof relate to a fluorescent probe and a preparation method and application thereof. It is to solve the existing CN detection ‑ The sensitivity of the fluorescent probe is low, and the fluorescent probe is not friendly to the environment. The structural formula of the coumarin functionalized graphene oxide reversible fluorescent probe is as follows: the preparation method comprises the following steps: and reacting graphene oxide with 3-epoxypropoxypropyltriethoxysilane to prepare an intermediate M1, and reacting the intermediate M1 with a coumarin derivative M2 to obtain the coumarin functionalized graphene oxide reversible fluorescent probe. The fluorescent probe can be used for detecting CN in a water system ‑ Detection limit of 3.5 × 10 ‑3 Mu mol/L, detecting CN ‑ Post-use Cu 2+ The solution is recovered and can be used in the field of water quality detection. |
