文摘Iron sulfide is an important reductive pollutant in aquatic sediment,so that increasing attentions have been paid to it in recent years.In this paper,the formation of iron sulfide in water-body sediment was introduced.Moreover,its adverse influences upon environment were summarized,including direct contribution to deficiency of dissolved oxygen in water,association with eutrophication in water-bodies and impact on geochemical sulfur cycle.Since conventional chemical analysis for iron sulfide has several disadvantages,new technique for rapid determination of iron sulfide on-line was prospected.
