近年来研究海洋中痕量元素的化学行为日益受到人们的重视。通过对海洋中痕量元素浓度的分布、元素与阴离子和有机配位体的络合作用、在微粒上的吸附、痕量金属离子的氧化还原反应等的研究,可以解决海洋地球化学中的一些重要问题。稀土元素的离子半径在痕量金属的海洋化学研究中起着独特的作用。 海洋中稀土元素的主要来源有:大陆上的稀土元素随江河流入海洋,含稀土的气溶胶溶解在海水中;海洋底部的热液作用。通过生物体的下沉过程,使稀
In recent years, the chemical behavior of trace elements in the ocean has been paid more and more attention. The study of the distribution of trace elements in the ocean, the complexation of elements with anions and organic ligands, the adsorption on microparticles and the redox reactions of trace metal ions can solve some of the problems in ocean geochemistry important question. The ionic radius of rare earth elements plays a unique role in the study of trace metals in marine chemistry. The main sources of rare earth elements in the oceans are: the rare earth elements in the continent flow into the sea with the rivers, the aerosols containing rare earths dissolve in the seawater, and the hydrothermal fluids act at the bottom of the ocean. Through the biological process of sinking, so dilute
