| Abstract: | A new acidification-blowing-absorption apparatus has been designed for the determination of sulfide. The preparative method and-stability of sulfide standard solution were also studied. The optimum analytical conditions have been founded, and the method lor the determination of sulfide by methylene blue photometric method has been established. The determination limit is 0.005mg S2-/1, and the range of determination is 0.005 to 0.700mg/l of sulfide using a 100 ml sample. This method is applicable to the determination of sulfide in water and wastewater. |
