一般认为只有含邻羟基醌的氧化苏木色精(Hematein)才与金属离子有颜色反应。光度分析上常把苏木色精(Hematoxylin)的乙醇水溶液经H_2O_2氧化,配制为氧化的苏木色精(Oxidized Hematoxylin)溶液使用。它已用于高灵敏度光度测定钼和钨,但选择性和颜色反应对比度(△λ)较差。商品试剂“Hematein”曾被用于萃取光度测定钼,以及在TritonX-100存在 It is generally accepted that only the oxidized hematein containing ortho-hydroxyquinone reacts with the metal ions. Photometric analysis often Hematoxylin (Hematoxylin) ethanol aqueous solution by H_2O_2 oxidation formulated as oxidized hematoxylin (Oxidized Hematoxylin) solution used. It has been used for high-sensitivity photometry of molybdenum and tungsten, but the selectivity and color reaction contrast (Δλ) is poor. The commercial reagent “Hematein” has been used for the extraction spectrophotometric determination of molybdenum, as well as for the presence of Triton X-100
