Roe与Kuether比色法是以脱氢抗坏血酸与2,4-二硝基苯肼结合生成带色脎为基础的一种总抗坏血酸的测定法,在定量过程中最重要的关键就是将抗坏化使之变为脱氢抗坏血酸。原法以活性碳为氧化剂,此活性碳对抗坏血酸氧化虽但其作用并非专一,因为在使抗坏血酸氧化的同时必然有其他物质被氧化。此外,能?
Roe and Kuether colorimetric dehydroascorbic acid is coupled with 2,4-dinitrophenylhydrazine to produce a color-based method of determination of total ascorbic acid, the most important key in the quantitative process is to anti-degeneration Make it dehydroascorbic acid. The original method of activated carbon as the oxidant, the activated carbon on ascorbate oxidation, but its role is not specific, as in the oxidation of ascorbic acid at the same time there must be other substances are oxidized. In addition, can?
