| Abstract: | In the alkaline medium, manganese()was oxidized to manganese() by air. In the phosphoric acid medium, manganese() reacts with diantipyryl|(p|methoxy)|phenylmethane(DApMM) to form a yellow product. The molar absorptivity is 5.4510+4 Lmol+{-1}cm+{-1} at 450 nm. Beers law is obeyed in the range of 020 g/25mL. This method can be applied to the determination of manganese in steel with satisfactory result. |
