It is based on the spectrophotometric measurement of Fe2+ complex with Ferrozine in NaAc_HAc buffer.
介绍了以菲咯嗪－醋酸钠－醋酸缓冲溶液为显色体系、用自制的铁含量比色测定仪快速测定工业用水中总铁含量的方法。
Se(Ⅳ) is reduced with KBH_4 solution to H_2Se which is absorbed by Ferrozine—Fe (Ⅲ) solution to form purple ferrozine—Fe (Ⅱ) chelate.
用 KBH_4溶液使 Se(Ⅳ)还原生成 H_2Se 而分离,用菲咯嗪铁(Ⅲ)的水溶液吸收,于560nm 波长测定被 H_2Se 还原生成的紫红色菲咯嗪铁(Ⅱ)配合物,可定量测定硒。
