Scope
This method is applicable to the soluble H2S, HS, S2 in surface water, groundwater and domestic sewage, papermaking wastewater, petrochemical wastewater, coking wastewater and printing and dyeing wastewater, as well as those existing in particulate matter. Determination of soluble sulfides and acid-soluble metal sulfides. When the sampling volume is 250ml, use 500ml of "hydrogen sulfide absorption chromogenic reagent" to measure with a 1cm cuvette, the minimum detection limit of sulfide is 0004mg/L, and the measurement concentration range is 0008~25mg/L.
