The invention explores the application of a transition metal organic framework material in the detection of anions in water. The experimental results show that the material has a certain fluorescence quenching effect on Cr 2 O 7 2‑ , CrO 4 2‑ , I ‑ , Br ‑ , Cl ‑ , HCO 3 ‑ , NO 3 ‑ , among which Cr(VI) (Cr 2 O 7 2- and CrO 4 2- ) have significant fluorescence quenching effect, and thus have the advantages of rapidity, simplicity and sensitivity in anion detection. |
