We have developed an ion chromatography (IC) assay using ultraviolet (UV) detection following post-column derivatization with ferric nitrate to determine phytate [inositol hexakis phosphate (iP6)] (1) (2) in wild rice samples and other diet composites.

Taft found that when one of these "iron-oxo" complexes reacts with ferric nitrate in a methanos solution, a green-brown color appears and then gives way to a yellow color when ether diffuses into the system.
