Development of an In Situ Analyzer for Iron in Deep Sea Environment

Abstract:

This study presents the development of an in-situ analyzer, ‘IonConExplorer’, which can detect iron concentration in deep seawater at maximum 4000 meters with the method of spectrophotometry coupling with liquid waveguide capillary cell. The detection of limit is 27.25nM (n=20) for Fe(II) at 562nm, while the linear range is 100 nM - 1 μM. On the whole linear range, relative standard deviation of the seven replicate measurements is less than 2%. IonConExplorer is composed of pressure house and equipressure house containing control unit and fluid system, respectively. Via TCP protocol of network communication protocol(TCP/IP) when connecting to the ocean observing network, IonConExplorer transfers abundant real time data instantly to the shore-based station, demonstrating high temporal and spatial distribution resolution of iron.
