于1988年6—7月在辽东湾进行了调查,对其沉积物间隙水中Fe~(2+),Mn~(2+)及有关参数的测定结果及相关分析表明,铁、锰平面与垂直分布类型的不同是由于Fe~(2+),Mn~(2+)氧化还原速率、扩散速度及控制体系不同的综合结果,得出Fe(Ⅱ,L)+S_2~(2-)→FeS_2(s)和Mn(Ⅳ,s)→Mn(Ⅱ,L)是控制辽东湾间隙水中Fe~(2+),Mn~(2+)浓度的主要体系,并用氧化还原界面层的一种简单模式讨论了铁、锰转移与其浓度-深度分布形状的关系。本文还应用Fick第一定律直接计算了沉积物-海水界面间铁、锰扩散转移通量。
The investigation of Fe ~ (2 +), Mn ~ (2+) and related parameters in the sediment interstitial water from June to July in 1988 showed that the correlation between iron and manganese flat and vertical The difference of distribution types is due to the comprehensive results of the redox rate, diffusion rate and control system of Fe ~ (2 +) and Mn ~ (2+). The results show that Fe (Ⅱ, L) + S_2 ~ (2-) → FeS_2 (s) and Mn (Ⅳ, s) → Mn (Ⅱ, L) are the main systems controlling Fe 2+ and Mn 2+ concentrations in Liaodong Bay interstitial water. The model discusses the relationship between iron and manganese transfer and its concentration-depth distribution. The Fick’s first law was also used to directly calculate the flux of iron and manganese diffusion at the sediment-sea interface.
