Study on the Determination of Manganese in Alloy Steel Materials by Spectrophotometry

Abstract:

With samples decomposed by mixed acid of sulfuric acid-phosphoric acid, manganese in alloy steel was determined by periodate spectrophotometry. The acid system for dissolving samples was established, and 525 nm as the optimal measuring wavelength was selected. The results showed that Beer's law was obeyed in range of 0 to 36μg/mL for manganese (II). The relative standard deviations were between 0.6% to 2.0%(n=6). The recoveries of samples were between 95.1to 101.4%.
