| Abstract: | The fluorescent characteristic of the colour reaction between dioxopromethaine hydrochloride and sulfuric acid has been studied.The experiment results indicated that dioxopromethaine hydrochloride was a weak fluorescent substance and could react with sulfuric acid to form an intense fluorescent substance.Combined with flow injection analysis and time scanning technology,a new flow-injection fluorescence method for the determination of dioxopromethaine hydrochloride was established.The experimental condition... |
