Indirect Determination of Sulfide in Wastewater By Flame Atomic Absorption Spectrophotometry

摘要

Sulfide in wastewater could usually be determined by iodimetric titration or by Para-ammino dimethylaniline colorimetry estimation, but sometimes it was not easy to do by these emthods. Because of some flaws such as trouble operation procedures, long analytical time and too many itnerference factors, based on the study project proposed by the Environmental Monitoring Center of the Ministry of Metallurgy, we used a qukc, stable and reliable method to determien surplus silver by Flame Atomic Absorption Spectrophotometry (FAAS), then to determine sulfide indirectly, We achieved good results by this way.
