Determination of atmospheric iron particulates by X-ray fluorescence spectroscopy.
A method is described for the determination of atmospheric iron particulates by X-ray fluorescence spectroscopy. Samples are collected, with a low-volume air sampler, on organic membranes which are used directly for measurement by comparison with standards prepared by precipitation of hydrous iron(III) oxide on similar membranes. The method is simple and rapid, and offers a precision and error of about 6% for the range 10-200 mug of iron.
