硫化物的

Consequently, sulphidic bottom waters on continental shelves may be more common than previously believed, and could therefore have an important but as yet neglected effect on benthic communities.

关于硫化物会被亚表层海水中的细菌完全耗尽、从而会被浅层沿海水域的遥感或监测活动忽略的发现表明，大陆架上含硫化物的海底水域也许要比我们所想的更普遍，所以有可能对底栖生物群落产生一个重要的、但以前却被忽略的影响。

Thermodynamic process of direct aluminium extraction from aluminium sub-sulphide, which is unstable and easily decomposed into Al and Al2O3 at a low temperature, was analytically studied. The temperature, at which alumina, FeS and carbon react to form aluminium sub-sulphide in different pressure, was evaluated with "Substance Gibbs' Free Energy Functional Determinant" method.

Other methods, such as high performance liquid chromatography, combustion -ion chromatography, polarography and nuclear magnetic resomance, can also be used.

此外，液相色谱法，燃烧-离子色谱法，极谱法和核磁共振法等也可用于硫化物的分析。

The results showed that loading Ag^＋, Ni^2＋, Cu^2＋ or Zn^2＋ ion on the activated carbon obviously improved its adsorption of benzothiophene, while loading Fe^3＋ or Co^3＋ ion on the activated carbon caused a decrease in its adsorption of benzothiophene in comparison with the original unloaded activated carbon, which was due to the variation of the nature of soft and hard acid on the surface of the activated carbon.

采用密度泛函数理论法计算结果表明，苯并噻吩的电负性χ为2.638，属软碱类物质；由于Ag^＋为软酸，活性炭负载Ag^＋离子，增加了其局部表面的软酸，从而增强了对苯并噻吩硫化物的吸附；由于Ni^2＋、Cu^2＋和Zn^2＋离子属交界酸，负载Ni^2＋、Cu^2＋、Zn^2＋离子增加了活性炭表面的交界酸，也在一定程度上提高了其表面对苯并噻吩硫化物的吸附；当活性炭表面负载了硬酸性Fe^3＋或Co^3＋离子，其局部表面硬酸增大从而降低了其对苯并噻吩的吸附。

This is the first time that large-scale detoxification of sulphidic waters by chemolithotrophs has been observed in an open-ocean system.

由RV Alexander von Humbolt在纳米比亚沿海水域获得数据显示，由含硫化物的海水覆盖的面积大约为7000平方公里的一个非洲沿海大陆架区域，因细菌的作用而消除了毒性：对生物有害的硫化物被氧化成无毒的胶体硫和硫酸盐。

The separation performance of these membranes for thiophenic sulfurs from n-hexane was evaluated. The competitive adsorption of thiophenic sulfurs on these membranes was investigated by varying the loaded ions, the ion concentration and the activation temperature. The regeneration of used membranes was also investigated.
