RAPID DETECTION METHOD OF SULFIDE CONTENT

摘要

A rapid detection method of sulfide content is provided, which includes determining the concentration and volume of a metal ion solution, the volume of a sample, and the amount of a chemical reducing agent, depending on a threshold value. It also provides preparing the metal ion solution, sampling the sample, and mixing the metal ion solution with the sample to result in a mixture solution. The chemical reducing agent is added into the mixture solution to obtain the resulting solution. Naked-eye observation of the resulting solution is used to determine whether the sulfide content of the sample is over the threshold value. When the resulting solution is clear, this indicates that the sulfide content of the sample is greater than or equal to the threshold value. When the resulting solution contains precipitates, this indicates that the sulfide content of the sample is lower than the threshold value.
