Conclusion The use of SPE procedures has been growing in the past few years due to their
advantages offered for trace element determinations, namely conservation of species, good …

Iron plays an important role in oceanic biogeochemistry and is known to limit biological

This manuscript overviews relevant scientific literature concerning speciation of trace
elements by using non-chromatographic methods. The main principles of the different …

The development of a highly sensitive system for the shipboard determination of dissolved
iron at the sub-nM level is presented. The technique is based on a flow injection method …

A new procedure for the direct determination of picomolar levels of iron in seawater is
