查询词典 potassium permanganate

The nitrite in food was converted to manganese bioxide precipitate by potassium permanganate under acid condition. The precipitate was dissolved in sulphuric acid and the absorptivity of manganese was determined by atomic absorption spectroscopy, so that the content of nitrite was obtained indirectly.
