  • 摘要: 本文主要研究了南黄海(32°N)沉积物间隙水中的Fe,Mn,Cu,Co,Ni与其硫化物及粘土矿物间的关系,结果表明:间隙水中的Mn2+,Cu2+硫化物趋向于沉淀,Co2+,Ni2+硫化物趋向于溶解,Fe2+则有其硫化物的溶解-沉淀控制,Mn2+,Cu2+还有其他体系和硫化物体系共同控制其浓度,间隙水中的Fe2+可被蒙脱石吸附,Mn2+被绿泥石吸附,Ca2+,Ni2+被蒙脱石、绿泥石吸附,Co2+被绿泥石、蒙脱石吸附,Fe2+,Mn2+对粘土矿物吸附剂的专属性要求远比Cu2+,Co2+,Ni2+高,蒙脱石是南黄海沉积物中最重要的阳离子吸附剂,绿泥石次之。
    Abstract: This paper emphasized on studying the relationships between Fe, Mn, Cu, Co, Ni and clay minerals in sediment interstitial waters of the South Yellow Sea. It was found that sulfides of Mn2+, Cu2+, tended to precipitate in interstitial waters. Sulfides of Co2+, Ni2t tended to dissolve, Fe2 + controlled by dissolution-precipitation of its sulfide.Fe2+ in interstitial waters could be adsorbed by mont-morillonite, Mn2+ by chlorite, Cu2+ and Ni2+ by montmorillonite and chlorite, Co2+ by chlorite and montmorillonite. Adsorption of Fe2+ and Mn2+ on clay mineral are more specific than Cu2+, Co2+ and Ni2+. Montmorillonite was found to be the most important and chlorite the second adsorbing agent in sediments of the South Yellow Sea.
