• A method has been described for the direct spectrophotometric determination of up to 40 μg. of iron (III) with DBM in the organic phase.<BR>An orange complex, which is formed with the addition of DBM and pyridine to the MIBK extract of iron, has a maximum absorbance at 410 mμ. The effect of the diluent on the color reaction has been studied; methanol has been selected as the best diluent of those tried. The color reaction conforms to Beer's law and has a sensitivity of 0.0046 μg. Fe/cm<SUP>2</SUP> for －log<I>T</I>=0.001. The effects of diverse ions on the determination of iron have been studied; it has been found that this method is simple and is sensitive and selective to iron.
