In the photometric determination of arsenic as to be molybdenum blue, phosphorus shows the same absorption as arsenic. Therefore, the determination of arsenic had to be studied after separation of arsenic from phosphorus. It was found that before the reduction to molybdenum blue, phosphorus in the form of molybdate alone was extracted with organic solvents, while arsenic salt was not extracted. Phosphorus molybdate was completely extracted with amyl alcohol in 0.1〜0.4N of sulfuric acid. This procedure was applied to the photometric determination of arsenic in iron and steel, and satisfactory results were obtained.
