Chloride ion fluorescence detection method and device, and use thereof

摘要

A chloride ion fluorescence detection method and device, and a use thereof. The chloride ion fluorescence detection method utilizes chloride ions to influence luminescence characteristics of some photoluminescent substances to change the emission spectrum of the photoluminescent substances. The concentration of the chloride ions is detected through two processes comprising the fiber surface film forming and test liquid preparation of a fluorescent reagent sensitive to the chloride ions and measurement of information of fluorescence peak wavelengths or intensities. The method can be applied to the online assessment of the corrosion environment of steel bar concrete or the measurement of chloride ions in a laboratory.
