Abstract

We have developed a new method to assess simultaneously the rates of biological reduction of Fe(III)-ligand complexes at nanomolar concentrations and iron uptake in marine phytoplankton. Other methods for measuring iron reduction require micromolar iron concentrations, which can saturate iron uptake in these organisms. In the present study, high sensitivity was obtained by combining radiometric techniques, ligand competition, and selective retention on solid phase extraction columns (C₁₈ Sep-Pak
