Abstract

A bathophenanthroline method was examined to determine microamounts of iron in water. Investigations were made with artificial standards of ferrous diammonium sulfate solution. Analytical procedure was similar to the Wilson's method [found in Analyst, 89, 389 (1964)] but pH adjustment was made with a glass-electrode pH-meter. Ferrous-bathophenanthroline complex was stable in isoamyl alcohol for more than twenty hours. Determinations could be available within the errors 0.4 μg/l (95% confidence limits). This value is smaller than that of authorized in JIS B 8224(1961).
