摘要
This article studies the reaction of Fe2+ and o-phenanthroline. Using ascorbic acid as the reducing agent, at pH 2 similar to 9, Beer's Law is obeyed in the range of 0 similar to 10 mu g/ml for Fe2+. And satisfactory results have been obtained in the determination of ferric oxide in cement and clinker.
