概要
- 論文の詳細を見る
A new AC polarographic method utilizing the methylene-blue procedure was used for the determination of the sulfide ion. By means of dimethyl-<I>p</I>-phenylenediamine sulfate and iron(III) alum, the sulfide ion is converted quantitatively into methylene blue in the sulfuric-acid milieu. The methylene blue thus formed shows a prominent and reproducible AC peak, which can be suitably utilized for the indirect microdetermination of the sulfide ion. Halide ions interfere with the determination, however.
