	烟台夹河口外柱状沉积物还原性无机硫、活性铁的变化特征及其相互关系期刊论文 OAI收割海洋科学, 2018, 卷号: 42, 期号: 8, 页码: 90-97 作者: 姜明; 赵国强; 李兆冉; 盛彦清 \| 收藏 \| 浏览/下载：25/0 \| 提交时间：2020/07/08 还原性无机硫活性铁深层柱状沉积物硫化度矿化度 Reduced inorganic sulfur Reactive iron Deep core sediments Degree of pyritization Degree of sulfidity The distribution characteristics and coupling mechanism of reduced inorganic sulfur (RIS)and reactive iron in marine core sediments are closely related to the evolution of environment quality.In this study,an improved cold diffusion method and hydrochloric acid extraction method were applied to the acid-volatile sulfur (AVS),pyrite sulfur (CRS),elemental sulfur (ES),and reactive iron [Fe (Ⅱ)and Fe (III)] analyses.The distribution characteristics and coupling mechanism of S and Fe were investigated based on a core sediment 4 meters deep collected in the northern sea area of the mouth of Jiahe River,Yantai.The results showed that the RIS in sediments was dominated by CRS,followed by AVS and ES.The content of AVS presented a narrow range with depth,whereas the CRS and ES were higher at the top and bottom layers than the middle layer reactive iron was dominated by Fe (II),which increased with depth,while Fe (Ⅲ)gradually decreased with depth.Most of the Fe (III)was reduced to the disssolved Fe(II),which was combined with the soluble H_2S of the sulfate-reducing bacteria to produce CRS and ES in the deep layer,resulting in their accumulation at the bottom of core sediments.Furthermore,this study showed that reactive iron was not a limiting factor for the accumulation of RIS with lower degree of pyritization and degree of sulfidity.
