吸光光度法测定双氧水中总碳含量

Spectrophotometric Determination of Total Carbon Content of Hydrogen Peroxide

用重铬酸钾氧化有机碳,产生的Cr3+含量与总碳(双氧水中的总碳基本上都是以有机物形式存在)含量成正比,可以间接测定双氧水中的总碳含量,结果准确可靠且操作方便。

Organic carbon oxidation with potassium dichromate,the content of the production of Cr3＋ and total carbon was proportional,and the total carbon was in the form of organic.The total content of hydrogen peroxide can be indirectly measured,with accurate result and convenient operation.
