A simplified 1,10‐phenanthroline technique suitable for the determination of dissolved iron in remote sources of water

Abstract

A simple technique is described for the determination of dissolved iron in water. It is useful for investigating remote sources and avoids errors due to post‐sampling precipitation of hydrated ferric oxides. A small sample is added to a mixed 1.10‐phenanthroline‐i‐acetate buffer solution in the field and this‘developed sample” can then be stored for up to 4 weeks before the absorbancc value is read.
