锰是白酒中卫生检验的重要理化指标之一 ,在白酒的卫生标准 (ＧＢ2 757- 81)中 ,锰的含量应≤2ｍｇ/Ｌ。常用的测定方法是 :(比色法 )样品经消化后 ,在酸性条件下 ,用过碘酸钾将二价锰氧化成七价锰呈紫红色 ,与标准液比较定量【1】。我们用 72 30型分光光度计比色测定 ,能直接 Manganese is one of the important physical and chemical indicators of health inspection in liquor. The content of manganese should be ≤2mg / L in the health standard of liquor (GB2 757-81). Commonly used assay is: (colorimetric) After the sample was digested, under acidic conditions, with potassium periodate oxidation of bivalent manganese into heptavalent manganese was purple, compared with the standard quantitative [1]. We use 72 30 spectrophotometer colorimetric determination, can be direct
