MARINE GEOCHEMISTRY APPROACHES OF RARE EARTH ELEMENTS IN COASTAL AND ESTUARIAL AREAS
- 海洋环境－已发表论文 
稀土元素对研究和探索水体许多宏观、微观过程能起到很好的表征作用。对河口水体痕量稀土元素分离、富集和测定进行了总结,综述了近岸和河口地区稀土元素元素化学研究的最新进展,讨论了稀土元素近岸和河口地区地球化学研究的意义,回顾了过去研究中的不足及其对后续研究工作的指导意义,并展望了近岸和河口地区稀土元素地球化学研究的发展方向。Rare Earth Elements (REEs) which form a coherent group of trace elements whose chemical properties change systematically across the series (La through Lu) are generally used to understand and investigate the geochemical processes of coastal and estuarial areas, which can be employed as geochemical tracer. In this paper, the reviews of separation, pre-concentration, and determination of trace rare earth elements (REEs) in estuarine water and seawater, as well as the approaches of REEs geochemical studies in coastal and estuarial areas and the interactions of REEs between water, suspended particle matter, and sediment in these areas are included. The trend of REEs geochemical research and possible investigation in coastal and estuarial areas are also suggested.
