- 論文の詳細を見る
The photometric determination of manganese described is based on the oxidation of the Mn to permanganate by means of persulphate, reaction with tetraphenyl-arsonium chloride, extraction of the complex with dichloroethane from 0.7 N sulphuric acid solution and measurement of the absorption of the extract at 528 nm. Manganese can be determined in the ppm-range in iron, steel, nickel, copper, aluminium and magnesium. Interferences are caused by larger concentrations of chromium.
