| Research Abstract |
For understanding of the biogeochemical cycles of iron in the ocean, a new in-situ analytical system was developed to determine picomolar of Fe(II) in seawater by using luminol chemiluminescence detection. The detection limit was about 10 pM. We successfully revealed the Fe(II) distributions in the surface waters of the Pacific Ocean with this system.
