Detection of halide ions
WebThe primary test for halide ions is generally used on solids, while the second confirmatory test is generally used on solutions of those solids. When concentrated sulfuric acid (H S O 2 4 a q) is used to detect halide ions, concentrated sulfuric acid is added dropwise to a solid sample. Any gas produced can initially be tested with damp blue ... WebThe present detection system was relatively sensitive to halide ions except for fluoride: other anions gave smaller signals than halide ions. The present detection system …

Considering the high importance of the rapid detection of chloride ion (Cl −) in sweat for the diagnosis of fibrotic cysts, we have investigated the heterogeneous halide exchange between CsPbBr 3 perovskite nanocrystals (PNCs) in n-hexane and Cl − in aqueous solution. The results show that CsPbBr 3 PNCs could …
